Evening all.
I get the following error trying to open any of our seven forums:

Fatal error: Call to undefined function suffusion_bbpress_content_class() in /nfs/c06/h06/mnt/154861/domains/athensown.biz/html/wp-content/themes/suffusionchild/single-forum.php on line 18

http://athensown.biz/community-forum/
wp version 4.1.1
bbPress version 2.5.6
Current Theme is SuffusionChild

So far, I deactivated all plugins except bbPress. No change
I deactivated and reactivated bbPress. No change
I reactivated all remaining plugins. No change

Bundled themes or not is still greek to me. I think the SuffusionChild is the only theme on the site.
Issue unchanged with twentythirteen, twentyfourteen, twentyfifteen, or suffusion. Well, now, I take that back, in previewing suffusion, I am able to open all the forums as long as I do it on the same tab. I get the error if I open a link in a new tab

Thanks,
Constantine

ok, the function that is being called is ‘suffusion_bbpress_content_class’ which tells us that this is a function created by the theme suffusion. bbpress functions start ‘bbp_’.

You have put (intentionally or not) a file into your child them called

‘wp-content/themes/suffusionchild/single-forum.php’

which is an amendment of bbpress’s single-forum.php.

After googling I found this post which seems to describe your issue and the resolution, which is to remove the bbpress files from your child theme.
