Bug #83430
Updated by Andreas Kienast over 6 years ago
Set @BE/showRefreshLoginPopup = true@ in your LocalConfiguration.php. Open / reload the TYPO3 backend. To skip the waiting process, open a console in your browser and trigger the timeout modal by calling @TYPO3.LoginRefresh.showTimeoutModal();@ manually.
A popup window will open and render a backend login form. After logging in, a new session is created within the popup.
Instead, the popup should close and revive the session in the main window.
