DNN 4.8.3. Site was working fine up to last Tuesday, 15th. Pages appear to be displaying without issues. Users are reporting that they are unable to login.
Click login link on home page and nothing happens (does not appear to postback).
Go to another page then click the login link and login page displays.
Enter username and password then click login and nothing happens (does not appear to postback).
Click "Forgot Password" and nothing happens (does not appear to postback).
I have checked the EventLog table and no entries are made.
I have restarted the application, recycled the application pool and run iisreset without success.
Any suggestions would be appreciated.

UPDATE:
Problem solved. I discovered that a user had attempted to paste script for google analytics into the PageHeadText on the home page. This became truncated causing a js error preventing postbacks.
What will users try next
