[Koha] Search results problem on upgrade from 3.14 to 17.11

Greetings, I have moved an old Koha library ver 3.14 to 17.11 (packages). This included changing to dom indexing as per the wiki. After rebuilding zebra I can search in the staff client and retrieve results ie. 12 result(s) found for 'kw,wrdl: pooh'. but all that displays is two boxes with Results and Location and nothing else. Searching at the OPAC returns no results. Any help would be appreciated. Clint.
