Hi,

I tried to install the Google Analytics package on Umbraco 4.7 in the backend. After the install my menu (top navigation) wasn't online anymore?

If I go to the XSLT file in my backend and want to save it again, it shows following failures:

Error occured

I deinstalled the package but the failure is still there and my menu isn't running anymore?

Does somebody could explain me why this happened?
