For some time i host some TYPO3 websites on my Debian Etch server with ISPConfig. The TYPO3 core is installed within /var/www and the website itself is installed within /var/www/webX/web/. The setup has been done according my Howto here: http://www.howtoforge.com/typo3_on_ispconfig I had never problems with this setup. Today, i migrated from php5mod to php5-cgi with suPHP. Everything went fine, cause i prepared this step very well. Now my server is running with suphp+php5-cgi and all the websites are up and running, no problems at all, except for the TYPO3 websites! When i visit a TYPO3 website an Internal error 500 occurs. Internal 500 errors are sometimes a little bit difficult to solve, but i am sure that it has something to do with permissions. Within this forum: http://www.typo3forum.net/forum/typo3-3-x-installation-und-updates/11596-typo3-suphp.html the same situation is described, but i do not understand the solution. (It is also in German). For me it is important that i solve this problem as soon as possible, because the TYPO3 sites are down. My /etc/log/suphp.log file shows me only a warning, which i understand: [warn] File "/var/www/typo3_src-4.0.4/index.php" is not in document root of Vhost "/var/www/web120/web" My /etc/log/apache2/access.log shows me: [13/Apr/2007:08:09:29 +0200] "GET / HTTP/1.0" 302 373 "-" "Apache/2.2.3 (Debian) mod_ssl/2.2.3 OpenSSL/0.9.8c mod_perl/2.0.2 Perl/v5.8.8 (internal dummy connection)" Can someone help me to solve this? Thanks in advance!
