I have just upgraded from photopost classifieds 2.6 to 3.21. I have two issues:
1.- during db upgrade from 3.0 to 3.1 I obtained the following error:
Error performing MySQL command: INSERT INTO pp_adtypes VALUES (4, 'Business', 0)
Error: Duplicate entry '4' for key 1
2.- when I try to translate using the phrases editor changes are not saved.
