Component/s: Support Toolkit
I have search a while, and there are many bugs but no solutions.
PM resync option
+ delete orphan PMs
+ delete PMs without entry in phpbb_privmsgs
+ recount all PMs and unreaded PMs
test it in includes/ucp/ucp_pm_viewfolder.php
and change here line:
than you found the lost PMs and you can delete it. But its hard... with an STK option it will be better to solve it for all users.
