Reply To: Import problem PHPbb – bbPress
As far as I know there are no issues importing from phpBB v3.0.11
This doc has any known issues when using the phpBB importer:
https://codex.bbpress.org/import-forums/phpbb/
Did your import fail at one point and you started the import again which would have caused duplicates?
To debug the issue further I would need some detailed information, particularly some SQL examples would be helpful.
If you still have issues after resting your forums and this constantly happpens please create a ticket on Trac https://bbpress.trac.wordpress.org/ with some detailed steps to reproduce the issue and I will take a look.
