Please, I think there is some incompatibility with WPMU Apointments+ Plugin and Salient Theme (5stars and 23.000 sales: http://themeforest.net/item/salient-responsive-multipurpose-theme/4363266).
Salient Portfolio does not work fine (http://clubesquipyrene.com) and the Appointments shortcode does not work inside Salient Portfolio (http://clubesquipyrene.com/portfolio/frederic-pros/).
I can handdle it outside portfolio, but I will love to do that inside there (http://clubesquipyrene.com/calendari/).
Any idea will be appreciated!! Really thanks.
