Hello Kyatric,
If I come to scirra.com (not logged in to forum), click on the upper right-hand link (tutorials), then click on random tutorial (or any of the other tutorial links), I get the error. If I am logged into the forum, I do not get the error and all the tutorials I clicked on so far seem to be in working order.
I am using FireFox 6.0.2
Here's what I get (sorry for such a big paste!
Server Error in '/' Application.
