ASP.NET errors

 

#1. There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined

Check .NET Framework version for app pool.

Projects developed in (2.0,3.0,3.5) should run under an Application Pool with .NET FRAMEWORK VERSION v2.0.50727 

Projects developed in 4.0 should run under an Application Pool with .NET FRAMEWORK VERSION v4.0.30319

#2. Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Make sure that "Enable 32 - Bit Applications" is set to false or true for the app pool, depending on System.Data.SQLite.dll

System.Data.SQLite.dll is a mixed assembly, i.e. it contains both managed code and native code. Therefore a particular System.Data.SQLite.dll is either x86 or x64, but never both.

#3. HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
