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

[clint.deckard]

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.
