I have a site with multi-typed contents (proposed event + news).
I have a 2nd site I try to add multi-typed content by "add an existing content" which is in the first site but it does not work "L'insertion du contenu est impossible, Cette zone n'autorise pas le type de contenu choisi (Événement proposé) Ce contenu ne peut être inséré ici.". I have no restrictions in the skin.
