Yeah, I got you covered. The most recent release of Joomla has a tiny bug in it that causes this. Kind of wish they had just released a new file but they didn't and are not going to.
There is a patch for this. It can be found here:
http://forum.joomla.org/index.php/topic,89865.0.html
The file is called "
admin.mambots.php.zip" and is attached to that topic.
Just unzip an upload to the correct directory overwriting any duplicate files to fix the bug.
Good luck to you and enjoy the new SearchBot.
