Ciao a tutti
ho caricato un sito su un server e quando provo ad accedere ad una pagina riservata che richiede il login, ricevo questo errore:
[CODE]

[CODE]

Il problema dovrebbe essere causato da delle classi di mysql(mysqlmembershiprovider) per gestire i ruoli degli utenti ecc che provano a scrivere l'eventlog

Il server ha come sistema operativo windows server 2008 r2, iis7 e framework 4.0

ho provato a cercare nel file machine.config il tag 'trustlevel', ma non ho trovato nulla.
ho provato a cambiare il registro di windows, ma niente.
grazie mille
