what is confusing me is that in
dashboard>settings>forums>single forum slug you have
discussion where I have forum, and it is this slug that is the extra one showing in the url.
Why you have discussion, I have no idea, I have not seen this before
all I can suggest is that it could be a theme or plugin issue issue, so you’ll need to test to find out which
Themes
As a test switch to a default theme such as twentyfifteen, and see if this fixes.
Plugins
Deactivate all but bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.
and see what is setting this to discussion
Then come back
