WebResource.axd not found

Question

Good morning everyone,
I transferred my domain to another provider and I discovered that the various RequiredValidators no longer work, the postback still starts when the button is pressed.

Inspecting the browser console I get the error that the WebResource.axd is not found.

I did some research on the internet but didn't find the solution.

With the previous provider everything worked fine.

Do I need to enable something on IIS?

I guess that you use the ScriptManager in the page and the "another provider" use ASP.NET 4.5 or above while former provider use ASP.NET 3.5 or below.

If my guess is correct, remove the ScriptManager form the page if possible.

If you cannot remove the ScriptManger, the script mapping to the ScriptManager is required to make the RequiredValidator work.
