1.5.6 Header Search Box

Search on my site doesn't work from the header search box. It simply gives no results even if I type exact same as the product.
http://shop.areyoufitenough.com/index.p ... egory=true

If I then use the search on the search page it DOES work. eg..
http://shop.areyoufitenough.com/index.p ... h=medicine

Then, if I try using the header search again on a page with results, it does not edit the search terms and just returns the same results as the page I was on.

I am using just the default install of OpenCart 1.5.6 so NOT using a theme. Not sure how to check if this is clean install or an upgrade.

If an upgrade, some timestamps will be older than the suite of new files -- some files are superseded, no longer used -- unless all were sent up at once from a local upgrade and the server happens not to honor preserving timestamps (or the ftp client was not set to preserve them).

You might try sending up fresh search.* files, into the /catalog/ tree, in case there were any corruptions in transfer earlier.
