Re: Upgrade Error

This is missing from my web.config file but when I add it in after outputCaching, my site fails to load.

Re: Upgrade Error

I am missing this from my web.config file but when I add it I get :

The configuration section 'folder' cannot be read because it is missing a section declaration

Thanks
