I have recently updated to 5.4. I have some forums restricted by SP user groups which are mapped and synched with WP roles. When a user tries to submit a post to one of these restricted forums they are getting Access Denied and their user is set to the Subscriber user group. If I re-synch with WP they are added back to the correct user group in SP. They can delete and edit posts without issue. Only when submitting new posts does this occur. I did prune the forums recently and ran the rebuild indexes on them. Not sure if that would have anything to do with it. Any suggestions?
Thanks.
