    For some odd reason, in the last 7 days this plugin has started off lining my entire website and these are the messages I get.

    WordPress is unable to establish a connection to Redis. This means that the connection information in your wp-config.php file are incorrect, or that the Redis server is not reachable.

    Error establishing a Redis connection
    READONLY You can’t write against a read only replica.

    Is the correct Redis host and port set?
    Is the Redis server running?
    If you need help, please read the installation instructions.

    To disable Redis, delete the object-cache.php file in the /wp-content/ directory

    I have been deleting the object-cache file but surely there must be a better permanent solution to this. I’ve been using your plugin for months.

    That means your replicated Redis setup has an issue. What configuration are you using?

    I appreciate your quick response. I followed the instructions in this PDF (inside a cloud account) to set up my Synology server. Until last week, the Container Manager configuration worked flawlessly for months.

    Ooof, not sure about that. Did you try restarting the Redis container, or recreating it?

    I’ve restarted the container again and its working for now, but I did that before and i think it only lasted 3 days before the object-cache.php solution appeared again.

    Here is a log of the errors before it stop from the Container Manager.
