Thanks for the great plugin, I was having a lot of problems getting results to display in a logical order and the weighting system you use really solves that.
I have one problem that I have just discovered on a development site I am working on at http://staging2.webxopt.com/. In the admin panel everything works fine, but when I use search on the site, no results are displayed eg search for "acne" and you won't see anything.
This could well be something to do with the theme I'm using which is Ultimatum (a theme builder), as there seems to be no code after the title either. It did work prior to installing the plugin though, so it seems a bit odd.
Any ideas on how I can solve it?
