Today, a colleague was having issues on his Facebook where things were not loading and when clicking on his messages and Notifications they were not loading.
Clearing the Chrome Browser Cache seemed to sort out the problem.
In Chrome click on the three dots at the top right to open the menu.
At the bottom of this screen click on the advanced options if they aren’t already open.
in the privacy section, click on the clear browsing cache button and in my case I selected the last hour option and selected everything BUT the passwords boxes.
Hit Ok and it seemed to sort out the issue.
