    I just upgraded to Pro and am now getting this error:

    “The Object Cache add-in file object-cache.php is not a W3 Total Cache drop-in. Remove it or disable Object Caching. <input type=”button” class=”button” value=”Yes, remove it for me” onclick=”w3tc_beforeupload_unbind(); document.location.href=’https://thefreedompeople.org/wp-admin/admin.php?page=w3tc_dashboard&w3tc_default_remove_add_in=objectcache&_wpnonce=932e28128e&#8217;;” />”

    We have our hosting on WPMUDEV.com and they have object caching. I am assuming this is why but not sure of the solution.

    Thank you

    Hello Brad,

    Thank you for reaching out, and I am happy to help!
    When the Object Cache is enabled in the W3 Total Cache, W3TC adds a drop-in file object-cache.php in the /wp-content/ folder
    If you are using any other form of Object Caching by any other plugin, it may also add the drop-in file with the same name to utilize persistent Object Caching.
    You can manually check the mentioned file and see if it’s added by the W3TC or any other plugin by opening the file directly in the cPanel or via any text editor.

    Please make sure to check with WPMUDEV.com if they are adding the drop-in file, in which case, you should disable the W3TC Object Caching, and if you want to use the Object Caching in the W3 Total Cache, make sure to disable the other one.

    Thanks!
