    Hi,

    I get the error message: "The Object Cache add-in file object-cache.php is not a W3 Total Cache drop-in. Remove it or disable Object Caching."

    Pressing the remove button doesn't solve the issue.

    Tried deactivating and reactivating the plugin with no luck.

    Any ideas?

    Thanks

    If you find object-cache.php file in your site's wp-content folder, then try re-naming it.

    Similar problem here. I just updated W3 Total Cache today, April 5. Right after the update, the error message shows up on the Plugins page and the Performance (W3 Total Cache) settings page: "The Object Cache add-in file object-cache.php is not a W3 Total Cache drop-in. Remove it or disable Object Caching."
    Please help.

    Just remove the file and W3TC will re-add it if needed.

    I got this error on an upgrade just now -- and it was a W3TC file but apparently out of date enough that it wasn't detected as such.

    Hi,

    i got the "The Object Cache add-in file object-cache.php is not a W3 Total Cache drop-in. Remove it or disable Object Caching." message some days ago, hit the "remove" button without any reaction. Today, i clicked "remove" again, which leads to a 500 server error, refreshing brought me a white screen and i cannot access dashboard anymore. website works.

    Login leads to a white admin page, but obviously i am logged in, because i can access admin panel in the frontend. But trying to empty any module via the admin panel leads to white page again.

    in the wp-content folder, there is no object-cache.php file. Any idea how to solve this? Thanks!

    Best regards,Sebastian.

    Try replacing object-cache.php with the file downloaded from https://wordpress.org/plugins/w3-total-cache/.

    This worked for me.

    If I deleted the file either manually or via pressing the remove button, W3TC would replace the file with an empty 0kb object-cache.php.
