What happens presently is....I am on a given screen. I attempt to make a change and save it. The save fails with a message (sorry I don't have the exact message) and I am taken to the ACP login screen. My username/pw is already entered so I press log-in, and I am taken back to the screen I was working with last. I then re-make the change and save, and then receive a message "Security error occurred. Please press back, refresh the page, and try again." When I press back I am taken back to the ACP login screen, I once again press login and then one again receive the same Security error message. I am caught in a loop and need to retype my URL to fix it.
This issue occurs for me on a daily basis so I can definitely duplicate the error if needed.
