Fatal error PDOException

[blacksrv]

Hi, I got this error after login to the backend:

Quote

Fatal error: Uncaught exception 'PDOException' with message 'You cannot serialize or unserialize PDO instances' in [no active file]:0 Stack trace: #0 [internal function]: PDO->__sleep() #1 {main} thrown in [no active file] on line 0

Already tried to delete cache, disable all modules, update processwire to lastest version, nothing works.

Any idea of this error?

Nevermind, was a stupid error on a prepend file.

I'm having the same problem today. What was your error?
