    Installing this plugin renders my site inoperable. Here’s the error log entry:

    Hi @hansgv

    Thank you for using our plugin!

    I am sorry to hear you are experiencing this error. I hav had a look at your error log and what I notice is the following line:
    PHP message: PHP Warning: include_once(/var/www/vhosts/mysite.com/wp-content/plugins/wp-rest-cache/wp-rest-cache.php): failed to open stream: No such file or directory in /var/www/vhosts/mysite.com/wp-content/mu-plugins/wp-rest-cache.php on line 25
    What it tells me is that the mu-plugin was successfully installed (in /var/www/vhosts/mysite.com/wp-content/mu-plugins/), but that it seems that the main plugin was not installed in /var/www/vhosts/mysite.com/wp-content/plugins/wp-rest-cache/. How did you install our plugin? And what did you do with it afterwards? Did you rename the plugin folder? And is your plugins folder indeed situated in /var/www/vhosts/mysite.com/wp-content/plugins/?

    Somehow the mu-plugin is there, WordPress is telling it that the wp-rest-cache plugin is in fact activated. But it cannot find the plugin files in the correct location.

    That’s exactly what I was wondering, but both /var/www/vhosts/mysite.com/wp-content/plugins/wp-rest-cache/ and /var/www/vhosts/mysite.com/wp-content/mu-plugins/wp-rest-cache.php exist.

    I installed the plugin straight from WordPress’ plugin directory.

    I first suspected this to be a caching conflict but neither disabling W3TC caches nor deleting the plugin and reinstalling it helped.

    The first message after enabling the plugin and reloading any admin page is a WordPress error: “You do not have sufficient permissions to access this admin page.”

    This is really strange. I tried to reproduce your error, but when I deliberately change the mu-plugin so it cannot find the plugin files anymore I do not get the “You do not have sufficient permissions” error. Instead I get: “There has been a critical error on your website. Please check your site admin email inbox for instructions.”. Which is what you might expect, since the fatal error is thrown.

    May I ask which other plugins you have installed? It almost seems as if there is a conflict.

    Hi @hansgv

    Thank you for the list, which is quite long… Unfortunately there are several paid plugins in your list, making it really hard for me to try to recreate your setup and trying to reproduce the error.

    The only thing left for me to advise you is to try deactivating all plugins and then reinstalling our plugin.

    Thread Starter hansgv

    (@hansgv)

    I disabled all w3-total-cache caches, disabled all plugins except w3-total-cache and classic-editor, and reinstalled the wp-rest-cache plugin. The issue still persists. Unable to log in afterward.

    After deleting wp-rest-cache again, I’m able to log in and see this error message:

    WP REST Cache: We have detected you are using external object caching. If you are using Memcache(d) as external object cache, please make sure you visit this plugin's settings page and check the "Using Memcache(d)" checkbox.

    I do use memcached with w3-total-cache’s Page, Database and Object Caches.

    Hi @hansgv

    You say: “After deleting wp-rest-cache again”, but you do get a notice from our plugin, so I don’t understand that part? What did you delete?

    About the notice: if you are indeed using W3TC with memcached and object caches, it is indeed advised to check the checkbox as mentioned in the message. This is because PHP’s memcached treats cache timeouts a little different and checking the checkbox will prevent any errors.

    I just meant that I have to delete the plugin to be able to log in again. That error message is visible at the first admin page load after deleting.

    Obviously I’m not able to check any settings boxes as the plugin has already had to be deleted. ??

    What file(s) did you actually delete? Because if you deleted the plugin, you should also not be able to see that notice since it is coming from the plugin. So apparently you did not delete the plugin.

    (By the way: you keep referring to the notice as an error, but it isn’t an error. It is a (dismissable) notice to let you know about the settings)

    Thread Starter hansgv

    (@hansgv)

    rm -R /var/www/vhosts/mysite.com/wp-content/plugins/wp-rest-cache/
    and
    rm /var/www/vhosts/mysite.com/wp-content/mu-plugins/wp-rest-cache.php

    That’s right, it’s not an error message. It might not even be relevant in any way. Just wanted to report everything that comes by.

    Hi @hansgv

    Well, those are the correct deletions, but are they really deleted? Because IF they were indeed deleted you would not be able to see the notice anymore, since the plugin that shows the notice is gone.

    Thread Starter hansgv

    (@hansgv)

    I think the probability of rm command failing silently is close to zero. ??

    Maybe the notice was just a cached item or something.

    I remain interested in your plugin and am happy to assist in debugging any way I can.

    Plugin Author Richard Korthuis

    (@rockfire)

    Unfortunately at this point I am unable to help you any further. I am unable to reproduce your error and from what you are telling me I don’t see anything wrong other than the fact that the must use plugin is unable to find the wp-rest-cache plugin.
