Hi,<br /> <br /> I have been using DotNetNuke 6.0.0 hosted on 1and1 running in Medium Trust. When I upgraded the upgrade page showed a successful upgrade across the board but when I access the site after this I get:<br /> <br /> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.<br /> <br /> Digging further by turning debugging on the error seems to come from the ClientResourceLoader in DotNetNuke.Web.Client.dll. (Full exception details below).<br /> <br /> Any help anyone can lend would be extremely helpful!<br /> <br /> Thanks,<br /> <br /> Alex.<br /> <br /> <h1>Server Error in '/' Application.<hr width="100%" size="1" color="silver" /> </h1> <h2> <i>Security Exception</i> </h2> <b> Description: </b>The application attempted to perform an operation not allowed by the security policy.

I was upgrading from version 05.06.02 to version 06.01.01. Tested everything local and worked fine, but when I wanted to upgrade on my hosting environment, I got the same problem.

I worked around the UpgradeWizard by surfing directly to Install/Install.aspx?mode=upgrade
Updated smoothly, but got the error when returning to my portal. Somebody who can help? Thx

Ok, seems like since version 6.1.x DNN is using DotNetNuke.Web.Client.ClientResourceManagement.

Problem occurs since this version in Medium Trust environments.
