Ok, I have been playing around and as soon as I choose not to allow CPU tasks in device profile manager I get the message about HTTP internal server error in boinc event log.

If I enable CPU computation on profiles manager on WCG, then I get new tasks for HCC GPU again....

Techs....do you have a part in this? Restricting the GPU WU flow for those running only HCC GPU or with app_info file?

I forget where but someone posted you also need to check if no work is available send work box.

I'm probably wrong but it's a thought.

Ok, something is very weird. Now I get this error when running default settings: allowing CPU work and having checked both HCC and HFCC and allowing work on my GPU also.

BOINC can still upload tasks, but not report them.
In event log I get:

2012-10-23 11:01:23 | World Community Grid | Scheduler request failed: HTTP internal server error

Anyone having the same issue? Should I try to upgrade BOINC to 7.0.31 even though it is still Beta? Running 7.0.28 now...

Oh, ok will try.
Also, why I was wondeirng about the BOINC version is since I for instance had a GPU WU reporting a runtime of 2 seconds (the initial CPU-phase takes usually 15-17 secs on my mahine). And my wingman had 0.03h of time reported on it. However it was marked as "Valid". Interesting...

If techs see this, this is the WU name
X0960070810639200606221647


EDIT:
Ok, I have tried clicking the update button in BOINC to get a new master file...and after a few tries I got it, but directly afterwards it is still the same problem:

None of the above, here... I had odd intermittency this morning [like hours no connection for anything WCG, no web, no forum, no Ready to Report clearing] and booted my Router which also acts as my DHCP/DNS server. After, all is zooming again. Possibly the intertubes are reshaking their pathways.
