I am trying to upgrade from 5.3.1 to 5.4.0 on an IIS7.5 and SQL Server 2008 Express platform.
After extracting the upgrade package and copying it over to my installation directory, I go to my site and get the following:
Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed
The web.config line that the site fails on is:
<add name="Compression" type="DotNetNuke.HttpModules.Compression.CompressionModule, DotNetNuke.HttpModules" />
Rolling back to 5.3.1, I check my permissions level and see that I have AspNetHostingPermission in the Host Dashboard.
Any help would be greatly appreciated.
