I update my Jomsocial to the latest 1.8.10 yesterday and now the GK JomSocial Members show the new registered users but take some hours to show them... I don´t know why the module takes many times to display the avatars...
Now I only have problems when I try to publish any joomla module on the right1 or right2 position on the jomsocial layout. (jomsocial frontpage only)
Thanks
Diego
