Hi,
All groups are accessible, except for one since the transition to version 4.9.1 :
.../index.php/les-groupes/viewgroup/13-tous-a-poil
redirects to this error:
0 - method_exists(): Argument #1 ($object_or_class) must be of type object|string, null given
Could you help me please ?
Sincerely,
Franck
