After having the server up and running fine for several weeks, I went in to make some changes and found that ISPConfig's interface appears completely broken.
Only parts of the interface are appearing, and it took several refreshes to be able to load the username and password fields to login.
This is what it looks like.
I've inherited this server and am not sure where to begin.
We are running several database/php driven sites on this server, and they are all functional, so it's not a simple matter of a totally broken php/mySql engine.
Edit: This server is at linode and was setup using the Perfect LAMP server guide from howtoforge.
Ubuntu 12.04 , PHP 5.3.10, ISPConfig ... I don't know as the normal buttons in the interface are missing.
I've done the steps outlined in http://www.faqforge.com/linux/debugg...-of-a-failure/
however without access to the full UI I was unable to change the errorlevel.
