Not sure if its been previouly reported but when enteing the search text end session it seems to cause an error in the site search engine.
If I understand you correctly you entered "end session" is the search - is that correct?
I have tried this out and it is working now for me - can you try again?
I have also seen this error - on occassion.
It seems to be only happening sometimes, which makes it difficult to find. But next time it happens, please reply here, including exact time of your search and search keywords. Then I might be able to track it down.
I have just used the keywords end session in the search field on the forums home page and the error occured. 23/03/09 09:25
I've had time to look a bit more into this and didn't find the problem, but I did find a few other key words giving the same error.
But I've reported the error to Telligent (the company behind Community Server) and I'm hoping for a quick answer.
