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.
- Which changes did you made before the issues started?
- Did you change any settings in php.ini like disabling functions?
- Which errors do you get in the apache error.log?
- Is name resolution working on your server? Try with e.g. "ping -c3 google.com"
Thiis is for debugging server issues but you have issues with the interface so this wont help anyway.
