HTTP Error 500.19 - Internal Server Error in BlogEngine.NET

I'm trying to install BlogEngine.NET in my Hosted Plan at arvixe.com

I get this error when I try to navigate to the Blog :

The configuration section 'system.web.extensions' cannot be read be开发者_运维问答cause it is missing a section declaration

53:     </system.serviceModel>
54:     <system.web.extensions>
55:         <scripting>

And here is my web.config file.

There is some articles on internet about get this fixed but the problem is :

1- I'm using the blog in a Hosted plan

2- I don't have access to the IIS configuration with Arvixe.

Do you think I can fixe this just by changing the web.config file ?

You need to tell your host to change the framework version your AppPool is tied to. Its probably tied to 2.0 which doesn't recognize system.web.extensions. It needs to be changed to 4.0

A couple of things to try:
If the OS is 64bit, try to recompile your application in Any to have it run as a 64bit application. Or change the Application Pool to enable 32bit applications.

If that doesn't help, perhaps the web.config section is locked down, and you will then have to ask your hosting company to allow the section.
