I have some problems like other users (SQL and no function on frontpage). I am using MTS (template manager), search field use his own code and of course the changes made in bm_search.php don't function, that is the reason of problems (is not a problem of contribution)
I managed to modify the MTS code and now SmartSuggest works like charm.
I am not an expert and maybe it is obvious for experienced user, but this can help other people.
