First how do I re-run the attachment part of the merge system. It failed due to a dns issue trying to copy the files. Alsoafter merge is there a way for users to mark all private messages as read?
Merged from phpbb3
The easiest way to rerun the merge would be to delete what was merged then do it again. Or you could risk just doing the attachments.
For the pm's you could run this SQL query:
UPDATE `mybb_privatemessages` SET `status` = '1'
It wont allow him to rerun just that part of the merge, he has to redo all of its dependencies too. Which means he should really just perform the whole merge over from the state everything was in prior to doing it the first time. Only this time with everything working properly.
Rerunning isn't really an option as it is already live minus attachments Ty though. As far as the pm's Ty very much that resolved it I think
