5.1 Password ProtectionLink to chapter 1
You have the option of enabling ‘Password Protection’ on any site. Unlike your WordPress credentials, which control access to a site’s admin areas, Password Protection controls access to an entire site, meaning only those who know the password can work on or view a site. It even hides a site from search engines.
This is useful when developing a new site that you don’t want yet publicly available on the web. You can share the username and password with clients or colleagues, but unauthorized admin users and the general public will not have access.
Password Protection uses Basic HTTP Authentication and does not use any WordPress usernames or login details.
Users who attempt to access any part of your site will see a login modal similar to the one in the image below. Only by entering the correct credentials will the user be allowed to proceed.
Click the On/Off feature in the Password Protection row to enable/disable the feature. Use the toggle to turn site protection on or off.
Once active, create a username and password you wish to apply to this site. A strong password will be generated, or you can add a custom password into the field. When activating or deactivating your password, click Change to save your changes.
5.2 Web Application Firewall (WAF)Link to chapter 2
Our Web Application Firewall (WAF) monitors the IP addresses and user agents attempting to access your site and filters out traffic that is known to be unsafe or that you have identified as unwanted.
The key distinction between our WAF and typical site security protocols is that a security plugin protects a site at the point of attack, whereas a WAF prevents unwanted traffic from ever reaching its intended target in the first place.
Our WAF protects sites from attacks such as cross-site request forgeries, cross-site-scripting (XSS), file inclusions, and SQL injections.
For additional steps in protecting your site, use Defender, and check out the Ultimate Guide to Security on the blog.
Configuring your WAF
A WAF requires all traffic to pass a set of rules that sits before traffic hits your WordPress site to help monitor and filter out attacks and malicious traffic. These policies aim to protect against vulnerabilities by filtering out malicious traffic. WPMU DEV has a custom set of WAF rules and allows you to add your own custom:
- IP Whitelist
- IP Blacklist
- User Agent Whitelist
- User Agent Blacklist
Click the On/Off feature in the Web Application Firewall row to enable/disable the feature, then click the toggle switch in the popup to access the configuration panel.
WPMU DEV maintains a set of rules that will identify and block known, unsafe traffic, but admins can whitelist (allow) or blacklist (block) IP addresses and user agents as they see fit using this configuration panel.
The IP or Internet Protocol address is a unique number that is linked to all online activity for a given user. You can block or grant access to specific machines, locations or users with the IP Whitelist/Blacklist fields.
You can Whitelist or Blacklist an IP address by entering it into the fields provided. Enter only one IP address per line, and click Change to save.
This makes it easy to block attacks quickly before they reach your server or whitelist your own IP or team member’s IP so they can bypass the WAF.
User Agent Whitelist/Blacklist
The user agent is the system information being used to access your site, including:
- The browser application name and version
- The host operating system and language
Often this information can be used to block a botnet that is originating from too many IPs to block but using the same User Agent for it’s attack. You can view visitor User Agents in your access log.
Use the Whitelist field if you need to allow a good bot that doesn’t use specific IPs to bypass firewall rules. Remember, User Agents can easily be spoofed by bots, so whitelisting them should be done only when you can’t whitelist by IPs.
You can Whitelist or Blacklist user agent by entering it into the fields provided. Enter only one agent per line, and click Change to save.
Remember, when activating or deactivating the WAF, click the Change button to save your changes.
WAF Logs for a specific site can be found in Hosting under the Logs tab.
Logs can be used to see where attacks are coming from, what requests were blocked, what rules those requests triggered, and changes that can be made to minimize false alarms. For example, if you are performing a valid action on your site and get blocked, you can find information on why in the WAF log and perhaps whitelist the IP or ask support to disable a specific firewall rule ID (coming soon). More information about the WAF Logs can be found under the Hosting > Logs document.
5.3 MultisiteLink to chapter 3
You can convert your site into a Multisite network by clicking the On/Off button in the Multisite row to open the configuration popup.
Once you’ve converted a site to a Multisite network, you cannot revert the site to a single site without migrating. So, before making the change, be sure converting to Multisite is the right move for your site.
If you are uncertain which Multisite installation– Subdirectory and Subdomain– is right for you, see our WordPress Multisite documentation for guidance.
Looking for help setting custom domain names for subsites on a Multisite network? Check out our domain mapping guide on the WPMU DEV blog.
When you’re ready, choose the Multisite installation you prefer and click Continue.
If you are absolutely certain you wish to continue, enter your WPMU DEV account password, check the Yes, convert my site to a Multisite box, and click Continue. The conversion begins immediately, and there is no way to stop it or easy way to revert the changes.
The time it takes to convert depends largely on the size of the site, but it could range from just a few seconds to several minutes. A success notification will appear in The Hub when the conversion is complete.
5.4 PHP VersionsLink to chapter 4
It is our policy to only provide support for the latest supported PHP versions. This is both to make sure our sites are secure, and to provide you with the fastest most performant hosting service we can!
Currently we default all newly-created sites to the latest release of PHP 7.3. Occasionally, some third party plugins may be out of date and cause issues with the latest version of PHP. In that case you can look for updates, alternatives, or worst case, we do support downgrading your PHP version to older ones that still provide security patches (currently PHP 7.2).
If you want to test your site’s compatibility with the latest version of PHP before upgrading, we recommend changing the PHP version in your staging environment and testing the functionality there first.
You can upgrade or downgrade your PHP version in the Hosting Overview screen or in the Tools tab. In either case, click the edit icon next to the current PHP version number, and a list of available supported PHP versions will be displayed in the dropdown.
Choose the version you wish to install, and click Apply.
5.5 DatabaseLink to chapter 5
WPMU DEV gives you access to easily edit and manage your Database from the phpMyAdmin database manager.
Making changes to a site’s database can break the site. Take care when making changes. Contact support if you have questions. Detailed documentation for phpMyAdmin can be found on the phpMyAdmin site.
From the Tools tab, click the Manage Database quicklink to open phpMyAdmin.
phpMyAdmin includes tools for managing and viewing databases:
- Status info
5.6 Object CacheLink to chapter 6
We leverage Object Cache at the database level, and this is enabled by default on all sites we host.
Object Cache improves performance by minimizing server load related to queries that are frequently called by WordPress, plugins, and themes. Because of this, you may need to clear Object Cache from your Hosting Hub after using a plugin that interacts directly with the database in ways outside of normal WordPress guidelines or if you make changes directly in your database using phpMyAdmin.
The object cache should only be flushed if absolutely necessary. It is usually not needed except after making direct database edits or during development. If you aren’t sure, contact support, and we’ll help you out.
To clear cache, click Flush in the Object Cache row.
A “Are you sure?” pop-up will verify you would like to clear your cache. Click Continue to flush object cache.
5.7 wp-config.php Constants ProtectionLink to chapter 7
Our hosting environments are designed to provide the best WordPress experience possible, so many of the workarounds members may have employed with other hosts are completely unnecessary and are automatically filtered.
Some wp-config.php modifications actually conflict with our system and will adversely affect both member sites and our hosting environments. These include cron jobs and modifications to the WordPress file system or memory limitations.
To ensure your scheduled tasks run on time, every time, WPMU DEV hosting environments utilize server-side crons (crontab) by default and call the WordPress scheduling system via WP-CLI every 5 minutes, eliminating the need for alternative cron usage or external services.
Our hosting environments leverage the default WordPress file system to achieve a sustainable balance between performance, security and stability. We understand that members may have been compelled to modify the file system to compensate for the shortcomings of other hosts, but those modifications are not necessary with WPMU DEV hosting and can cause significant issues server-side. Therefore, we do not allow modifications to the wp-content name directory via FS_constants like FTP.
WPMU DEV hosting allows memory limits (WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT) of 256MB for Bronze and Silver plans, while Gold and Platinum plans are allowed 512MB.
Modifications to the following constants will be removed:
Modifications to the following constants will be filtered:
5.8 Reset wp-configLink to chapter 8
This file is located in the root of your WordPress file directory and contains your website’s base configuration details, such as database-connection information. If you migrated a site from another host, this information might need to be reset.
Clicking reset will open the “Rest wp-config.php” confirmation pop-up. This will reset your wp-config.php back to the default state, and anything you have added or changed in it will be lost.
Click the Confirm Reset button to reset the wp-config.php file or the X or Cancel to close without saving your changes.
5.9 Migrate Existing SiteLink to chapter 9
- During migration, the source site overwrites everything on the destination site, including all content, plugins, themes and settings. Be sure this is what you want before proceeding.
- If you don’t have (S)FTP access to the site you want to migrate here, you should be able to create (S)FTP credentials in your current host’s control panel. Or you can try automated site migration with our Shipper plugin, instead.
To Migrate to a new Hub-connected site, click the Begin Migration link in the Migrate Existing Site row. From the dropdown, choose a location from the dropdown to migrate to.
If you don’t see the site you wish to migrate to, Add it to your Hub first and refresh the list.
Click Next to continue.
On the next screen, enter the (S)FTP credentials for your site. You should be able to view or create (S)FTP credentials in your current host’s control panel, or you can try migrating with the Shipper plugin instead.
Once you’ve entered the information, click Start Migration to continue.
If you encounter any issues with migrating your site or using or configuring the Tools, Members have 24/7 support and site migration assistance.
