Question pagination problem

Hello. I migrated joomla website with kunena from 1.5 to 3.3.6
All are ok but the i have problem at pagination from kunena. On j 1.5 and kunena 1.5.6 the links was category/post/page-2.html
On j 3.3 and kunena 3.0.7 the links are category/post.html?start=20
I use sh404sef on old and new website but with this enabled or not, the links are same.
Thank for any response.

Please read K 3.0.6 + J! 3.3.4 pagination number links not returning to first page of topics and Problem return to page 1 for the official advice from the developers about your problem

please add kunena report

I don't have prb with back to first page (thank's to 810). My problem is the form of seo links in browser:
J 1.5 - www.prostemcell.ro/47-discutii-pe-bune/2...te-tarii/Page-2.html

and same link in
j 3.3 - www.prostemcell.ro/joomla3/47-discutii-p...tml?lang=ro&start=15

Is about "Page-2.html" vs. "?lang=ro&start=15"
The google has indexed from 2006 the first example type links and now, if everyone come from google got 404 error
