Hi,
Not sure when this happened as I now turned on search. Site is now on 7.2.1 but the same issue was found on 7.1.2 as well.

When searching I get to the search result page but at that page receive and error:

"A critical error has occurred. Sequence contains no matching element"

It blows up in the form "searchresults.ascx.cs" on this line:

IEnumerable crawlerList =
InternalSearchController.Instance.GetSearchContentSourceList(portalId);

I've been all over the place looking for settings that I might have missed but can't find anything that affects this issue.

So any pointers in the right direction are more that welcome.

Thanks in advance,
Mikael
