I'm trying to convert a phpbb2 installation to a phpbb3.3.0.
I have installed a new installation of phpbb3.3.0. When I run the convert script I get multiple duplicate entry errors (Duplicate entry '<id>' for key 'PRIMARY' code => 1062) in the 'phpbb_attachments' table. Has anyone else experienced this? Does anyone have any suggestions what I can do to solve it?
