I have the same issue. Basically, the “Forums” button in the main navigation no longer stays highlighted once you enter any part of the forums.
I dumped Firefox after version 4.6 and switched to Chrome. The difference was molasses vs. grease. It ain’t what it used to be.
Any chance support for other Forums are going to be added? I really need a converter for my Forum which is using the CMS from Seditio. Unfortunately, Seditio is not around anymore, but a fork exists at http://www.cotonti.com.
I have over 1500 members and 40K posts. I really want to get away from that CMS and convert to WP as it’s not supported any longer. Please advise, and if there is anything I can do to help, please let me know. Thanks.
