Cannot remove the plugin

    Hi,

    A while ago I installed the plugin as my hosting provider announced support for REDIS object cache. I installed it, enabled it, it was working fine but I could not see any performance-gain with tests.
    I kept it enabled for some months, then disabled it but kept updating it ‘just in case’. Then decided to do a cleanup of unnecessary plugins and decided REDIS plugin needed to go too.

    So I went to settings, disabled the Object cache, then to my list of plugin and clicked ‘Disable’ plugin – all fine. Then I clicked ‘Delete plugin’ and here is where the problems start:

    It won’t delete. I click the link to delete the plugin, then the server seems to be working on it, then nothing. It just stays as a disabled plugin in my plugin list.
    It also does not matter if I keep the necessary code in my wp-config file or not.

    So I searched online and found “you’ll need to make sure to delete the object-cache.php file in the wp-content/ directory.” (as per this post: https://www.ads-software.com/support/topic/wp-redis-is-corrupting-my-site-how-can-i-delete-it/) but I do not have such a file in my wp-content directory.

    So I decided to do what one does when faced with a difficult problem: I used force. I manually deleted the redis plugin directory using FTP. The result is that I cannot use the back-end of WP anymore, it gives a white screen of death.
    When I put the redis plugin folder back (yes, I made sure to back it up) into the plugins-folder the WP backend comes back to life. But I still have a disabled REDIS-plugin I cannot get rid of.

    Any help would be greatly appreciated.

    Hi @fritsje,

    sorry you’re having issues.

    If you’re not seeing performance gains from enabling Redis, then your Redis Server is misconfigured, or you’re not taking the performance measurements properly, or WordPress isn’t actually using Redis.

    Anyhow, you MUST delete the /wp-content/object-cache.php file first, when deleting /wp-content/plugins/redis-cache via (S)FTP.

    If you’re certain that you don’t have a /wp-content/object-cache.php file, then please post your error log to see what’s breaking when you deleted the plugin by hand.

    Thanks for your quick reply.

    If you’re not seeing performance gains from enabling Redis, then your Redis Server is misconfigured, or you’re not taking the performance measurements properly, or WordPress isn’t actually using Redis.

    Or all of the above, including me not being smart enough to understand how it (cache) works (I would fit into the category described in the ‘Read this before your post’-group, the ones that should talk to a developer).

    But anyway; I was all setup to remove the plugin directory using FTP, to get a white screen of death on WP backend, and getting the error-log info from my server.

    So I updated WP first this morning to the latest version, to be sure to not have any errors from that.
    And then I removed the plugin folder using FTP, and went to my WP dashboard… and all seems to be fine.

    I am not sure what is now causing it to be working without error (indeed: no errors in my log), but my guess is it has to do with the WP update I did, because I do not know what else to pin it to. I created the problem multiple times before posting the TS here, and now I cannot recreate it, unfortunately.

    I thank you however for your offered support and I will mark this issue as ‘resolved’.

    Kind regards,

    Frits
