- Login to the client area and download a new fresh copy of the latest PHP Live! software.
- Update your current PHP Live! system with the new files (the standard upgrade process by replacing the existing files with the new files).
- Launch the browser and clear the browser cookies
(for Google Chrome, there is an addon to clear the cookies for just the domain, example Edit This Cookie for Google Chrome).
