- After upgrading Umbraco you might get a blank page.
Potential solutions are:
- Emptying out the fileDependencyExtensions attribute in the ClientDependency.config file in the Config folder of the web root and restarting the web page.
- Upload your local Umbraco folder to the server replacing the files.
To prevent this from happening in the first place you should remove your umbraco folder from source control. If you use git you should add the folder to .gitignore and remove the folder from git.
