I am having a very unusual problem with the Trip Search module that has never ocurred before on previous Drupal installations I've done. (I've used this module several times, as I think it's way superior to the core search.) When I type a keyword into the input box on http://mysite.com/trip_search, the page refreshes but no results are displayed - I mean, nothing on the page changes at all, it just "rolls over".

But if I check my logs, it says the search results were successfully delivered, and the link in the logs - http://mysite.com/trip_search/?keys=british - will bring up all the search results for "british" on the results page. Also, if I manually type anything after "/?keys=" in the URL, the results for that term will display.

I've checked my page output, and all the actions on the search forms are resolving to the correct URL, so I know that's not the problem. I've even tried tinkering with the attributes of a static form, to see if that would work, with no luck. Has anyone else had this problem? BTW, I'm using Drupal version 4.7.6 in this instance. My thanks in advance for any help anyone can offer.
