I've just upgraded from 3.5 to 3.6 and, having amended priveleges, upgraded the DB - so Admin appears OK.
 
However, when I access the site I receive a 'DB ERROR 1052' error. (match_type ambigous)
http://www.noahs-arc.org.uk/

Apologies - User error - again!
 
I'd uploaded all of the Folders and their contents but forgot the root free-standing files.
 
OK now.
