    What's the default caching ? How to disable it for a upgrade?

    I noticed tonight upgrading my forum I had to open a "incognito" session to get the upgrade script to run.

    Zend Opcache caches PHP until you restart PHP-FPM which is probably want o you ran into ?

    Using any forum addon's for caching like Redis or Memcached for Xenforo etc ? If so just restart those services too before doing upgrades from file changes.

    I've not configured the centminmod package from defaults. So just a restart of PHP-FPM and then start the upgrade and I should be good? Thanks!
