Hi,

I have recently migrated my website to Umbraco 8 and Umbraco Contour didnt seem to work on Umbraco 8, so I uninstalled it and tried to install Umbraco since since I read that it uses the same license file as Contour but it seems to be breaking my website.

Error stack:

-> Umbraco.Core.Exceptions.BootFailedException: Boot failed.
