Polylang + Buddypress compatibility

Hello support,

I’m developping an Intranet site and I’m having compatibility troubles between Polylang and Buddypress i guess : when Polylang is activated, my members and groups pages dont show anything. (when i deactivate Polylang, everything is fine with my members page and my group page…and i dont have any other problems on any other pages when using Polylang (i can switch a language to another, everything works perfectly, the problem is only on members and groups page as i said…)
Does anyone of you know where it comes from ? And how to fix that ?
Thx by advance for your help dear support, i will be really thanksful if you can give me any kind of help,
Regards,
Oliver.
