Hi,
we are permanently getting the following error when a user tries to add a new topic:

[InvalidOperationException: Sequence contains no elements]
System.Linq.Enumerable.First(IEnumerable`1 source) +446

OS: Windows Server 2003 R2 x64 SP2 (IIS 6.0)

In fact the new topic is saved, go to the forum overview the topic is there. I can open it and post an answer (without error). Is this a known issue?

Thx for help.

.


I can't reproduce it. Maybe an integration issue.

Bingo! You are right; We use Deutsch(Deutschland) setting. I switched to English(United States), and guess what? It worked.

BUT, to make it more complex for you. :twisted:

When I switched back to Deutsch(Deutschland), the error did not reappear. So maybe this is an installation issue.

By the way, there is another language issue. When you are not loged in, there is the following text on top of the page:
