I have two forums where the title of those forums and all their threads don't display. I found support some discussions where templates can be modified to cause this but we didn't modify any. Here are two forums and their threads with no title. Viewing the source you'll see there is no H1.
But all the other threads on my site display the title/H1. Here is an example.
I am using "nodes as tabs" and it is the latest tab we created (P3) that isn't working but not sure that has anything to do with it. Is there a setting somewhere that I a missing?
