Background Tasks won't run.

[SJ77]

I upgraded from IP3.4.7 to RC5
the initial update seemed to go alright however, the background tasks error out to blank white screen.

Checked server error logs, nothing is being recorded.

Any idea what could be going on?
 

I have a request in for support but I am still waiting, thought I would open it up to others in case someone has some information.

Thank you
