There are no errors in the console in Firebug and all other JS related functions work correctly in WP Admin.
It’s for a regular installation of WP.
I was going to start on a plugin but wanted to check if there was a fix available.
The only way I could get WP and bbPress to integrate (also using the built-in bbPress integration setup) was using the WP Root Cookie plugin.
I tried all of the wp-config and bb-config modifications and none of them worked. The issue goes back to the beginning posts from this thread with the cookie domain issue.
