I've setup a new ISPConfig3 3.0.5 SP5 server with Apache mod_security as well. mod_security has been setup according this howto: After a succesful installation of mod_security, all websites are still up and running, which is nice. But...i am unable to access the ISPConfig webpage. Instead of the ISPConfig3 logon screen i see an error message with a warning that i am not allowed to enter the index.php page. What could be the reason and how can i solve this?
