bbPress.org

I had the EXACT same problem…

In bb_includes/template-functions.php

there were several references to bb_user_can ‘write-post’ and ‘write-topic’… however, when comparing this to the capabilities.php doc in bb_includes/backpress/capabilities.php, these capabilities are defined with the strings in plural: ‘write-posts’ and ‘write-topics’… in the template_functions.php doc, I changed all the references… and now all is peachy!
