Thanks for the info. We are aware of this, and hae already made the changes to fix it in next release.

i get this error too in some page
Notice: Only variables should be assigned by reference in /home/********/domains/**********/public_html/plugins/user/coursegroups/coursegroups.php on line 33

Please install latest version of coursegroups, as that error was already fixed.

Hola Antonio,
Yo tengo también ese error pero no tengo instalado coursegroups.
¿Alguna solución?...
Gracias
