No. I mean that the account you log into WP with is the one you log into bb with. That bb gets its users from wp_users and not bb_users. The plugin gets your user id, then sets that to be the active user in bb. I guess if the user id is present in both tables it doesn’t really matter, you might just be posting with the wrong account. Hmm, maybe that’s not even a requirement. Cool.
Anyway! Why won’t you talk about finding out the error message? That’s the only way to fix this.
If you like, I can make you a custom version that will echo everything it’s doing. It wouldn’t be as useful but it would do the job.
