Right after the overwrite of previous version files by the unzip in the administration, PHP engine might still have old files in cache. We do not want to use the cache and force reload of all application files. Thus we need to disable opcache.

For example, on the server I'm testing upgrade from 13.8.0 to 14.0.0, I get in the database:

MariaDB [tmp_pwgmig]> select * from piwigo_upgrade order by applied desc limit 10;

Obviously upgrade 165 couldn't be applied in Piwigo 13.8.0. It's a new upgrade script in Piwigo 14!

Piwigo think we're on 13.8.0 because the old include/constants.inc.php is still in opcache. Same problem for sub-files of Smarty.
