My settings for this modification are not updating. All other modifications update fine. The modification will save all settings, but modules, and ONLY if I disable all the modules.

THE PSIStats page remains blank as well.

vb activity is looking better and better all the time...

Good News:
A stable beta of vBExperience 4.0 will be released this week.

vBExperience 4.0 has all features of vBExperience 3.8 like Rankings, Awards, Achievements, Promotions and of course the virtual Shop. Additionally it has been tight integrated into vBulletin 4.0 Forums and Publishing Suite look and feel.

Support for addons will be included as soon as vBExperience 4.0 development reaches final stage.

Upgrading from vBulletin 3.8 is very easy, just importing the Product XML, recount and all is done.

superb Marius! :D

By any chance can you release the final stable version for the 3.8 series?

You said you had a Beta 4.

I've attached Beta 4, the last version for vBulletin 3.8 - Please don't install it in productive environment. No support for this.

Thanks.

Does it fix bugs from the previous Beta?

Yes. I'm using it on my demo site. But it does not mean it works perfect on *your* forum. ;)

So if im having problems with Beta 3, than installing Beta 4 cant hurt any worse can it.?
I'm at the point where i need to uninstall anyway.
(Profiles are not accessable at all right now)

Upgrade to Beta 4, as this is the most stable 3.8.5 - I'm running this since September 2009 on my mainsite. If you upgrade correctly all files, the GetActivity Error should disappear.
