I've got a dev site running under http://dev.vacancysoft.com/
As you go there you can see the error and I really searched the web for the solution but couldn't find any.
It all started with the UID and GUID in suphp.conf. When I changed the values both to 0 (because the error was previous that the values are to high) the new one appeared and I don't know how to go through.
Any suggestions? (I am a begginer so please describe everything which is more advanced).
Cheers!
Update
The main site is down too, now the problem is really urgent.
