I am an old VBScript and PHP programmer and have never dealt with ASP.NET, so please take it easy on me. I am simply trying to migrate website from an Azure server to an AWS instance. I was able to install the Telerik and change the assembly references in web.config, but now I'm getting this mismatch error and cannot figure out why. I have updated my versions and PublicKeyTokens everywhere I can find, and it still isn't working. Any insight would be greatly appreciated.
