There apparently are forum problems from time to time. We're looking into this. It's abit hard to track down as we haven't seen any error ourselves.

I've recycled the app-pool, perhaps that makes things go away. Nothing in the code has been changed for a long time so it's kind of strange.

We've uploaded a forum build which contains an error logger and which opens a form if an exception occurs. This forum currently runs as a debug build to get as much info as possible about the weird errors we might see.

If you see the exception occured form, please be so kind to fill in any additional information you might think that's useful to use to track down the error.

Thanks and sorry for this inconvenience.

Ok, I think I already found it.

Last weekend we added a lastvisitdate cookie to the downloads section of the site. Unfortunately, it has the same name, as the cookie on the forum. As the date format was different, it caused the date parser to crash.

We now run a potential fix for this.
