Can’t login after enabling object cache

Hello,

For some reason. I can’t login into WordPress after I enable object caching and have to disable it.

I don’t know if it’s related, but I can’t flush the cache once it’s enabled (get an error saying “Object cache could not be flushed.”)

I tried wp cache flush and redis-cli flushall.

I tried to disable all my plugin. I also didn’t find any errors in the Apache or redis-server logs.

I noticed that the file object-cache.php doesn’t get created in /wp-content. I only have the advanced-cache.php

Finally, here’s the result when I run diagnostic after enabling the cache. Thanks a lot for your help.
