I get the following Stack Trace when I try to run my site

Exception Details: System.Runtime.InteropServices.COMException: Invalid
class string


[COMException (0x800401f3): Invalid class string]

I have checked the <caches> in web.config but it is OK
Don't know what to do...

Yigit,

My first thoughts would be to make sure mscscache.dll and any other DLL
associated with a cache object are registered properly. You may be able to
use Regmon from Sysinternals (www.sysinternals.com) to trace the access to
the registry to see what Cache loader program ID that it's trying to access.

Cheers,
Colin
