Please help me. I started a server with ispconfig on debian etch. I secured the server with suphp. All done with the manuals here. But now, i got a big error. I moved my last page to the server and now, THIS site doesnt work. All the other Sites work, a smaller Joomla Site, too. But this Joomla Page doesn't. I checked out the memory and i saw, the webuser of the page causes 30-40 php5-cgi processes with hundrets of MBs Memory Usage. The Page timed out with a 500 error. i checked all the permissions but the error.log still gives me just one error: [Fri Apr 18 08:41:30 2008] [error] [client x.x.x.x] Premature end of script headers: index.php But all the permissions are correct! And the Page runs out of memory. Can you help me how to find the reason? is there a logfile i didnt find? How can i locate the script, which causes the error?
