bbPress.org

We had a PHPBB many years ago, which we migrated to bbPress around four years ago, but it seems some flags remained in the database for the whole time, flags like (_bbp_class, _bbp_old_user_id, _bbp_password, _bbp_phpbb_user_avatar, _bbp_phpbb_user_sig). They might be needed; I have no idea.

But after the last update of WP and all the plugins, all the migrated users started to get an error message instead of being able to log in:
`
{“success”:false,”data”:[{“code”:”bbp_converter_db_connection_failed”,”message”:”Database connection failed”}]}
`
After some debugging and searching, I found https://bbpress.trac.wordpress.org/ticket/3419#no0 and tried to remove _bbp_class, which helped 🙂

I just needed to wipe the SQLite Object Cache because it kept the old data. It might happen to someone else in the future, I don’t know. I don’t know if you can somehow influence that this metadata is not stored there or something else. But at least you have the information that it might happen.
