My Joomla back-end has suddenly locked me out: every time I go to /administrator/ the page simply reloads—no “username or password incorrect” warning, no lock-out notice, just an endless redirect. I have already: • reset the Super User credentials directly in the database through phpMyAdmin, • cleared cache, cookies, sessions, and • followed every recovery step documented on the Joomla site and suggested by ChatGPT. Nothing has worked and there have been no recent extension installs, updates, or core file changes, so the root cause is still unknown. I need a Joomla developer who can: 1. diagnose the redirect behaviour, 2. restore normal administrator access without touching front-end content, and 3. document the fix so I can avoid the issue in future. Access to cPanel, phpMyAdmin, and the file system will be provided immediately. Once you finish, I should be able to log in with a working username and password and stay inside the administrator dashboard without being redirected.
