  1. I am running a DotNetNuke web site on my Winhost site. This website uses a "Store" application that has a gateway to PayPal. When I process an order through PayPal everything works well on that side, but upon return to the webiste it get the following error message and the process stops.
    System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

    at NEvoWeb.Modules.NB_Store.Gateway.GatewayPayPal.AutoResponse(Int32 PortalID, HttpRequest Request)
    The action that failed was:
    The type of the first permission that failed was:
    The Zone of the assembly that failed was:

    Research says to use "Trust Level = Full" in the web.config file. I've done that and still get the error.

    Any ideas on how to resolve this issue?
