SymptomsSmarterMail (SmarterStats) fails to be used as default component. The following error is displayed:
"An error occurred during the processing of a configuration file required to service this request. Please, review the specific error details below and modify your configuration file appropriately. Parser Error Message: Unverifiable assembly 'Nevron.GraphicsGL' failed policy check."
ResolutionThe problem is that the current security policy does not allow processing the assemblies required for the proper application work. To solve this, log in to Plesk, goto Server, ASP.NET. In the Code Access Security section select FullCAS trust level. Then, log in to SmarterMail (SmarterStats) and activate it.
After that,go back to Plesk, Server, Components Management and set SM (SS) as default.
Now, the server-wide CAS trust level can be turned to its previous state.
