Hi, i'm using ispconfig 3.0.5.4p8 in Ubuntu 14.04 with apache and php-fpm. In this server i don't use mail, dns or the mysql support integrated in ispconfig. In one of my website i sometimes have errors like this: PHP Warning: realpath(): open_basedir restriction in effect. File (PATH_TO_FILE) It's a joomla website, the problem is that the filename is that the PATH_TO_FILE is related to a different website's folder on the same server. The problem disappear on server reboot. I searched the whole site and database for wrong file reference, but i can't fing anything. Does it is possible that the php process assign the wrong folder in some way? Thanks
Try to disable php opcache in PHP and then restart php-fpm and apache. There were some reports about this opcache bug here in the forum recently and there is a pending bug report in the tracker at php.net. Other caches like xcache dont suffer from that issue.
