I didnt do the php upgrade myself so im not sure whats happend exactly but its a CentOS 5.5 box on php 5.3.5. Basically now i have the following problems squirrlemail complains about a missing config file that is actually there. I cannot see any permissions problems? phpmyadmin was setup to use http auth, this now will not work I had to change it to cookie and now it does. php on all websites seems to be broken. I get 500 internal server errors. I have done upgrade.php in the ispconfig install folder with no change. I dont even have any log files to post up for this one.. it just doesnt seem to want to work. I cant see anything crazy in the config files. - Edit, this seems to be an suexec issue visiting /webmail/ gets me ==> /var/log/httpd/access_log <== 217.xx.xx.x - - [27/Jan/2011:19:51:12 +0000] "GET /webmail/ HTTP/1.1" 200 176 "-" "Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:126.96.36.199) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3" ==> /var/log/httpd/suexec.log <== [2011-01-27 19:51:12]: uid: (5006/web1) gid: (5008/5008) cmd: php-cgi-starter and just the websites index.php ==> /var/log/httpd/access_log <== 217.xx.xx.xx - - [27/Jan/2011:19:52:30 +0000] "GET /index.php HTTP/1.1" 404 - "-" "Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:188.8.131.52) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3" ==> /var/log/httpd/suexec.log <== [2011-01-27 19:52:30]: uid: (5006/web1) gid: (5008/5008) cmd: php5-cgi [2011-01-27 19:52:30]: target uid/gid (5006/5008) mismatch with directory (5006/5008) or program (0/0) So its some kind of permissions error?
