Hello,

I installed the latest version of Nextcloud with Apache, PHP 8.2, and MySQL 8.4.

I configured the memory cache in the config.php file.

If I add these lines:

```auto
'memcache.locking' => '\\OC\\Memcache\\Redis',
'filelocking.enabled' => 'true',
'redis' =>
array (
'host' => '/var/run/redis/redis.sock',
'port' => 0,
'timeout' => 0.0,
),

```

The message indicating that the memory cache is not configured disappears, but  
I cannot delete files or access my folders mounted as external storage.

If I remove the lines, the memory cache is not configured, but I can delete files and access external storage.

Thanks for your help 🙂

you don’t gave any information of your log files in your post but you can start to try disabling the filelocking.enabled from true to false …
