I have a site that has been working fine (unchanged for ages) and it has just been moved to a new server the site works but no css is being loaded and in the console it says:

Refused to apply style from DependencyHandler.axd?s=L2Nzcy9zY3JlZW4ubWluLmNzczs&t=Css&cdv=44 because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled

. Viewing the url directly gives a 404 error. Anyone know what needs to be changed on the server to get this to work? Other sites on the same server are working.

In your web.config file, is there a node for clientDependency? If so, does it look like the line below?

<clientDependency configSource="config\ClientDependency.config" />

@Stewart I am not 100% on the cause but I changed a few things on the new server to match the previous and it is now working: -Updated the app pool back to App pool identity and set permissions -Disabled Dynamic content compression as this was not installed on the previous server. -Restored the web.config from the old server
