Thank you. I removed it without negatively affecting WordPress.
@Malfhok: Try logging out, clearing your browser’s cookies/temporary files and logging in again. Is your login session transferred to bbPress/Wordpress?
Because I didn’t want to lose my cookies within Firefox (which made me falsely believe that the integration was still working), I tried logging in through Internet Explorer and it was then that I noticed the broken integration.
I didn’t give any thought to my bbPress 0.9.0.2 installation before upgrading my WordPress 2.5.1 installation to v2.6. Before the upgrade, the integration was perfect. I didn’t notice the “broken” integration since my browser was set to remember my login information, but once I visited this forum, threads like these forced me to investigate and realize the sad truth!
I hope an update to bbPress comes soon.
Use the bbPress Latest Discussions plugin for WordPress. It may not have been updated in a while, but it still works with WordPress 2.6 and bbPress 0.9.0.2.
BTW, WordPress 2.6 breaks login integration with bbPress 0.9.0.2. Look out for a bbPress update soon.
