Invalid Argument on Special:Search
Invalid argument for foreach on line 95
When using the full Special:Search page, you can get an invalid argument error if no namespaces are selected to search in. The search results are then relevant to the entire forum and not the wiki. This error is invisible to users, when redirect messages are turned off, although they may become confused with the search results.
Added an error message to force users to select a namespace when none is selected on that particular form.
