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:

https://msdn.microsoft.com/en-us/library/dd483478.aspx - section "To manually upgrade an application's Web.config file from the .NET Framework 3.5 to the .NET Framework 4"
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
This issue has nothing to do with your .NET Framework version. Your web.config file is not correctly formed. this section pages, shouldn't be there.
Thank you for sharing this with our forum community.
