Thank you for responding.
What is confusing is that I have two local installations of WordPress and two local websites.
In one of the installation’s WordPress Admin I can see Forums panel in Buddypress config, on the other one I cannot.
Anyway the only reason I wanted to access Forums Panel was to be able to enable Site-wide Forums.
With no Forums panel how do I do it ?
on the Forums panel I had two options Forums for group and New! Site Wide Forums.
