    Dear experts,

    I have recently been encountering the following error:

    “Internal Server Error
    The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

    More information about this error may be available in the server error log.

    Apache/2.4.41 (Unix) Server at http://www.ansareditingandconsulting.co.uk Port 80”

    My web host provider hasn’t really been that helpful, but I think I have located the source of the problem: W3 Total Cache. Ever since I deactivated this plugin, my website has been running fine. I recently adjusted some of the settings on WTC to improve my page speed but I cannot recall what changes I made, but I think whatever changes I made caused the error message.

    Can anyone advise on how I can activate WTC and apply the correct setting to optimise my page speed without resulting in an internal server error? Also, I do not have access to the error log from my end.

    The page I need help with: [log in to see the link]

    Hello @nalmufachi

    I am sorry about the issue you are experiencing and I am happy to assist you with this.

    Please completely remove and re-install W3 Total Cache:
    1. Purge Cache
    2. Deactivate and Delete Plugin
    3. Check .htaccess File (make backup)
    W3TC will create many directives in .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.
    Ensure that no residual entries are left over in your .htaccess file after deleting the plugin.
    4. Delete wp-content files and folders
    – cache folder
    – w3tc-config folder
    – object-cache.php (if exists)
    – advanced-cache.php (if exists)
    – dbcache.php (if exists)
    – upgrade folder
    – delete w3-total-cache folder in wp-content/plugins/ (if exists)
    5. Delete Cached Files from CDN (if using CDN)
    Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled the minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser.
    6. Go to your wp dashboard and re-install W3 Total Cache
    7. Enable Page Cache and Browser Cache and check your website.
    8. enable the other settings one by one and make sure to save all settings and purge the cache after each setting is enabled and check your website.
    If you experience any kind of issue just ever the settings back.
    I hope this helps.
