Website Login Issue Fix

My site’s login page has stopped working and users can no longer get past it. I need an experienced developer to dive into the existing code, identify the root cause, and restore a fully functional sign-in flow. At the moment I’m not sure whether the problem sits in the front-end form, the server-side authentication logic, or a session/cookie setting, so I’m looking for someone comfortable tracing issues end-to-end—HTML/CSS/JS through to whatever back-end language, database, and authentication library is in play. Once you have the environment running locally or on a staging branch, please: • reproduce the bug so we both see the exact failure • isolate the faulty component (form validation, API call, database query, session handling, etc.) • implement and test the fix across modern desktop and mobile browsers • push the corrected code back to the repo (or provide a clean patch) and confirm that new logins, existing accounts, and logouts all work smoothly I’ll be available to give you repo access, current hosting credentials, and any framework details you need as soon as we start.
