Thanks, Choufi. And there’s to need to apologize for your English! I’ll try it out.
I’ll point out one possibly related problem. The BP installation won’t take the default theme. The drop-down menu keeps reverting to the parent themes in P General Settings. If BP can’t find a usable theme, if can’t find the content.
I’m having the same problem. When I click the forums button in BuddyPress, I get an error 404 page. I’ve tried reinstalling. BuddyPress and the BBPress integration.
