Basic Search Function Versus Searchanise

Been reading all the posts about Searchanise, good and bad, mostly bad it seems.

My question is does the basic function still work or has it been removed (4.0.3)? The basic search function in my store does not work at all. The results page is just blank, the header and footer show but nothing in the main content at all.

Searchanise drop box widget works fine, but when I go to “view all results” from the searchanise drop box, I get the same empty results page as when trying to use the default basic search.

Makes me wonder if there is something wrong with the results page, anyone else experiencing this?
