thx Till, I understand all that now but please have a look at my second post: http://howtoforge.com/forums/showpos...55&postcount=2
the value that shows up is nowhere in my php.ini files !?
The point is hte problem could have been there for a while, I just realized it today as I did a /etc/ini.t/apache force-reload
oh, I rememebred: one of hte last changes I did, a whiel ago was add these: /etc/squirrelmail:/usr/share/squirrelmail:/usr/share/xcache/admin:/var/www/piwik to the custom PHP open_basedir - that shouldn't matter with this problem surely?
