Does the problem persist when you disable all other plugins and switch to a core theme?
If I recall correctly, this can be caused by a plugin or theme adding whitespace at the very start of the XML results, making it invalid XML and thus treated as there were no search results. The culprit is usually a poorly written theme or plugin.
I have same problem with kleesman.
I deactive all the plugins and ı tried with other theme but still there is problem for search panel.
Actually it was working first time on the my theme but suddenly works stopped.
Jason I think this problem is not currently plugins problem.
Can you think about this again? Please try to help us ı think this not only our problem with klessman.
Thanks for your attention.

I have the same problem. Someone found a possible solution?
The fix in the thread I posted here likely addresses the problem of search not finding any items. Have you tried it?
