THANK YOU for this post!
I cannot remember if this defaults to both being enable at the same time, but if they are, bbPress should consider adding some notes about this in the Settings.
Thanks again! Dale
We are having this same issue!
Did you ever get an answer to this?
We have very few plugins running on our site and we’ve tried disabling pretty much all of them but to no avail.
Please let me know if you received an answer.
