From Advanced Security of demo2025 project, I enabled Disallow concurrent login, then re-generate ALL the script files.
Open browser Microsoft Edge, login using username nancy. Everything is fine here.Open browser Google Chrome, login using username nancy, too. System will display error message: User ‘nancy’ already logged in, and so far so good.
However, if you pay attention more closely, you will see in Sidebar or top right of Navbar, its user’s picture is shown up, as if username nancy seems successfully logged in, even though when you try to click another menu item, then system will prevent it and display error message: Your session has expired.Thoughts?
