I hope all is well. I need your help please. I just install

I hope all is well.
I need your help please.
I just install and activated W3 Total Cache on my WP multisite and immediately after activating it I lost access to my site completely. i can't access the front end nor the back end of the site.

I am trying not to freak-out.

the most recent backup is 45 days old and it is not a complete backup.
I went ahead and created a complete site backup for the site after the problem hoping you can help me with this problem.

Any thoughts?

    Hi George,

    Sorry to hear of the problem you are having.

    You can just try deactivating W3 Total Cache plugin by renaming the plugin folder in the wp-content/plugins directory.

    Find more information about how to uninstall this plugin on the following page.


    The 500—Internal Server Error occurs when the Web server (running the Web Site) encountered an unexpected condition that prevented it from fulfilling the request by the client for access to the requested URL.

    Could you please check whether the answers provided on the following pages help you to fix this issue or not?


    Best Regards,
    Vinod Dalvi

    Hi there @George

    I hope you're having a great day!

    I see that you have removed define( 'WP_CACHE', 'true' ); from your wp-config.php. That's good. :slight_smile:

    But I also see that you have added define( 'SUNRISE', 'on' ); in the wrong place in wp-config.php. Please move that line to just above the line that says /* That's all, stop editing! Happy blogging. */

    Also, you have not removed the W3 Total Cache code added to your htacess file. You must remove it. Your htaccess should contain only this:

    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    # add a trailing slash to /wp-admin
    RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^ - [L]
    RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
    RewriteRule ^(.*\.php)$ $1 [L]
    RewriteRule . index.php [L]

    Finally, please be sure that you have deleted the files mentioned in those instructions:


    ...and delete the w3tc folder from wp-content

    Hello Patrick,
    I hope you are having a wonderful day.
    I want to thank you first for your help.
    Your directions fixed the problem and I have access to the post and pages.

    Can you advise me on how to prevent this problem from happening again.
    What is the best way to completely backup the system? Is there a trusted plugin you recommend? I do not want to worry about breaking the website every time I install a plugin.

    Is there a trusted way to speed the system?

    Is there a way to find out what plugin is slowing down the system?

    Thank again for all your help.

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
