[Dis2022-registration] fee payment credit card link

Dear organizers, I'm trying to pay the conference fee by card through the link https://matricula.usc.es/autoliquidacions/Frm_Economica_Autoliquidaciones... Once I fill the form as described in indico, I get the error message " 500 - Error interno del servidor. Hay un problema con el recurso que busca y no se puede mostrar. " Can you help me? Thanks, Giancarlo Panizzo
