Hello,
Your web.config file is not correctly formed. The error message is explaining the issue well enough. You can have a look at the following articles for more information:

Hi,.... I have clearly mentioned my .NET Framework as 4.5 as it has different web.config tags in that...........Please reply if you know this version
