I have two ISPConfig 3 servers (perfect setup, CentOS 5.5), one of them is 64 bit, and the other - 32 bit. While everything is fine with the 64-bit one, I have a weird problem with the 32-bit one. When I click on the webmail link from the panel I get 500 Internal Server Error, the address showing, for example, is: http://server1.example.com:8080/mail/webmailer.php?id=27 At the same time, if I just enter in browser: http://www.a-hosted-site.com/webmail I get successfully redirected to: http://www.a-hosted-site.com/webmail/src/login.php that shows SquirrelMail login. And if I enter http://server1.example.com/webmail/ I get 500 Internal Server Error again. I did the server configuration the same way (following the perfect setup), and this problem is really killing me. What could be wrong with the 32-bit version? Thanks for your help!
