Ok, so I reinstalled ISPConfig3 and the issue is not there! So I went back to check the rest of my website and database to see if it was a file system permission issue or a mysql issue. i dont see any issues with the filesystem however I did notice today that I'm getting kicked out of phpmyadmin with the same 403 forbidden /phpmyadmin/ error.
Weird! It was all running fine
If someone can point me in the right direction that would be great. Is there somthing with mysql and my remote calls to it that are not right? Again my setup is the multi server setup in the ISPConfig3 manual. All seperate servers pointing back to the main ISPConfig3 server.
