    I’m regularly getting PHP Warning messages 

    PHP Warning:  opendir(/.../htdocs/champagne/wp-content/cache/db/options//6a6): Failed to open directory: No such file or directory in /.../htdocs/champagne/wp-content/plugins/w3-total-cache/Util_File.php on line 158

    This happens on several sites I’m running W3TC.

    These messages have in common that the path contains two slashes in a row // meaning it’s an invalid path.

    Maybe you could track down the source of the call which passes these invalid paths or catch and ignore the issue in Utils_File.php

    Thanks,
    Marc

    Hello @luxxor

    Thank you for reaching out and I am happy to help!
    Can you please confirm that you are using Disk caching for DB caching module?
    Do you have an option to use any memory-based caching like Redis or Memcached?

    Thanks!
