Thanks, but I had version 3.0.0, and upgrade now to 3.0.9. Database updated, and modded PHBPP original files from 0. I have a few topic with password, and my users cannot open passworded forums.
I rebuilded my site, but all topics is closed, and my users wait a (temporary) solution, and I will not open passworded topics.
I search a solution while your version not ready, because I have two forums with many passworded topics, and we here is...
I think this problem in functions.php modded code, when login to topic, but I don't where.
