Solution to blank screen when trying to read messages
Recently we had a problem where any messages received could not be viewed in Firefox, Chrome, Edge or Brave. No matter which browser we tried on two different machines, whenever we would click to view the message received the screen would display the spinning 'wait' indicator then error out to a blank screen. We called tech support for a solution, many options were offered. Everything we were told to try (e.g. clearing cookies, history, cold start, etc.) did not help. Then trying it on our son's PC the messages appeared, and they appeared when my wife logged in thru her phone.
The solution came when it was remembered we had loaded a "hosts" file to assist in blocking spyware sites and big tech telemetry collection. My husband replaced the hosts file with an empty one - VOILA! The messages could now be viewed in any of the browsers.
The hosts file is located at:
Hope this helps someone who experiences a similar problem.😀
