Bug: Laracast login message appears again if back if initiated

After logging on and being redirected to the latest page, I got the 'Your Logged On' message, I then went to another page.

When i then pressed the browser back button, the log in pop message popped up again. I repeated the process and went to another page then back but, and again it still happened.

To add to this its effecting all pop ups, as after i posted this discussion, then got the pop up confirmation, i then clicked the back button, then the forward button, then the pop up notification happened again.

on MAC Pro using Chrome 43
