title: [AbstractProvider.GetProvider]: The object type '....' is missing the provider type configuration
body: <p>I keep getting this error on our dev and qa environments in a Kentico 9.0 mvc application that I created.  I did find this site that recommends that you clear out the temporary asp.net folders to fix the issue, (<a href="http://devnet.kentico.com/questions/error-cms-document-is-missing-the-provider-type-configuration" rel="nofollow noreferrer">http://devnet.kentico.com/questions/error-cms-document-is-missing-the-provider-type-configuration</a>) and this fixes the issue for a short period of time but after an hour or so the error comes back. I'm not having this issue on my local box at all and I've triple checked all the area's where I have the class name in strings.  </p>
  
  <p>We are running a weird configuration though, we've got one site setup and 2 applications setup under that one site. One for kentico and one for our mvc app which interacts with kentico. Both have their own application pool and are using Integrated Pipeline Mode.</p>
  
  <p>Any ideas??</p>
