Site Keeps Going Down. Help!

Hello WPMUDEV,

We recently pushed our site live, but it keeps going down :slight_frown:

I have been using your WP Smush to lighten the load on the database and I wanted to use your Hummingbird performance plugin as well, but the site keeps going down!

When it goes down I have to rename the plugins folder and one-by-one activate the plugins to build the site back.

I thought maybe you guys would know how to repair this.

As always, thanks for your help,
luke

    Hello Luke,

    I'm sorry to hear you're having these issues with your site.

    I've run your site through https://tools.pingdom.com/ and I'm seeing a very large number of chrome-extension:// references that are timing out. Inspecting your source, I'm seeing references like the following:

    <script src="chrome-extension://.../cast_sender.js"></script>

    Where ... replaces the actual string.

    This is very unusual to see in a webpage. Have you added these references yourself?

    Everything else in Pingdom tools looks very good, but the above references are causing timeouts and may be contributing to the problems you are seeing.

    Did you add these references?

    Best regards,

    James Morris

    Thanks James!

    We did not add any chrome extension references to the site. Very strange.

    Is there a way to have these removed?

    By the way, your WPMUDEV site optimization plugins are a huge help. Really appreciate them :slight_smile:

    Let me know what I should do. Thanks a ton!!

    Hello Luke

    When you say the site is going down, do you mean the server down or just the site down? If just the site down, then would you please check error log to see the error? I assume it could be low memory. What is your memory limit?

    And if you have mysql server down, then still you have to increase your primary memory or you need to increase size of swap partition.

    Let me know about this please.

    Have a good day!

    Cheers

    Hi Ash,

    Most often I get this message: Error establishing a database connection

    On our hosting cPanel the error log has a considerable feed. I can send that to you.

    Currently:
    PHP memory_limit = 256M

    Thanks for helping us out with this,
    Luke

    The site is down 50% of the time, and if anyone visits it, it goes down.

    Not sure if the "performance" tab on the hub is giving us the correct info. Right now the performance tab says our website has a score of 100! That would be awesome!

    But the site is nearly impossible to pull up. It takes nearly a min to load fully.

    We installed your Hummingbird plugin, configured it and we are hoping the plugin can either determine the issue, or fix it. That would be totally awesome too :wink:

    Please have a look, if you can, thanks!
    Luke

    Hello Luke,

    I apologize for the delay in getting back to you on this issue.

    I think the key clue here is the following:

    Most often I get this message: Error establishing a database connection

    This kind of symptom is usually due to insufficient MySQL (database) resources or a poorly coded plugin that is causing heavy MySQL queries. In order to get a better idea of what is going on though, I would need access to your hosting control panel and website so I can do some inspecting to see what your MySQL configuration is and what kind of load is being presented on the server.

    Would you please grant me access to your site and server?
