I have the same issue. I tried your advice and created the same user with the same password, made that user an admin in wordpress and then performed the following in order:
1. logged out of my dashboard
2. logged back in as the new user that matches the phpbb login
3. activated the plugin and then the bridge
Now everything I click in the admin panel takes me to my forums login section. If i’m logged out of the forums when I click links in the admin panel in wordpress I get redirected to my forums with this message:
“You have been successfully logged out.”
If i’m logged in as the new user I get:
“You were not logged out, as the request did not match your session. Please contact the board administrator if you continue to experience problems.”
If I check the wordpress site I’m logged in as admin instead of the new user I created even though before activating the plugin and the bridge I made sure to be logged in as the new user, not admin.
If I then attempt to log out of admin from the wordpress site I get redirected back to the forums with this:
“You were not logged out, as the request did not match your session. Please contact the board administrator if you continue to experience problems.”
I can’t login as the new user until I disable the plugin via the database. Rinse repeat.
I have a bit of a strange setup so Im curious if this might have anything to do with it. While my forums and wordpress are installed on the same server, the databases are not. The forums use a MSSQL ODBC connection to another server whereas wordpress uses a local MySQL database. Think that might be my issue?
