Oh, Thank you !
Sometimes when you experiment problems you just don’t remember to do simples and rationals things like that…
The problem comes from the default plugin “DB Cache Reloaded Fix”. I have desactivated all plugin when I activate only “DB Cache” at the first step of a group creation it create 2 “entries” of the futur group. When is desactivate groups works fine.
Do you know what caching plugin do this thing ? It’s important to have one, or I can build my site without it ?
