    Hello @mrcezars

    Thank you for reaching out and I am happy to help!

    This may have to do with the fact that most of the modules have the Disk caching method enabled.
    Can you please manually delete the /cache/ folder, and in the General settings disable the Object Cahcing and DB Caching if enabled, save all settings and purge the cache.
    Check if the problem persits.
    It’s nor recommended to use DB Caching and Object Caching if the only caching method available is Disk. I would recommend using Redis or Memcached in this case.

    Thanks!

    Hello @mrcezars

    Sorry for the late reply.

    Yes, you can delete the cache folder while the pulgin is deactivated. Once it’s you re-activate it, please disable the OC and DB Cahing

    As for the Redis or Memcached, these are not plugins, these are php extensions or memory-based caching methods that can be installed on the server and used with the W3 Total Cache to store cached files in the memory instead of Disk.
    Please let me know if you can reach out to your hosting provider and check this

    Thanks!

    Hello @mrcezars

    Thank you for your feedback.
    if you installed Redis on your server, you can use it with DB Caching or Object Caching (I recommend only using OC ) with Redis as a caching method.

    This will help with the load and store the cache in the memory instead of disk

    Thanks!
