After upgrading to 7.3.4 everything is working, but now after I give administrator rights to someone,

I can give and delete rights with no problem, The issue I have is that even after it shows that hey have admin rights, they cant see anything that an admin is supposed to see. They keep seeing things as regular users. (they already log off, and log in but it is the same).

chrome shows some interesting errors when choosing an effective date:

and on my logs I have:

[Thread:9][FATAL] DotNetNuke.Web.Common.Internal.DotNetNukeHttpApplication - System.Web.HttpException (0x80004005): This is an invalid webresource request.
   at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

So far, from what I have read it seems like its an issue with Telerik.Web.UI.WebResource (something not correctly set up on my web config maybe?), but Im not quite sure if that is what causing people to not have admin rights like they are supposed to.

any pointers would be great.

ran the script, some rows were updated. Still the same issue, user sees the site like a regular user. We also have a custom sign in module, Im wondering if it could be causing issue? or is there anything else related to roles being applied?
