Our staff can reach the login screen for https://theabduz.com/innovate-office/ but, as soon as credentials are posted to /innovate-office/login.php, the server throws a 500 error and the process stops. I need you to trace and eliminate the root cause so users land on the dashboard normally. Key facts • Current PHP version is unknown to me, so please confirm it first and adjust your fix for either 7.4 or any 8-series build. • No recent changes have been made to the server configuration or the application code. • I am not sure whether I can reach every log file myself, so be ready to guide me through granting you cPanel or SSH access to error_log, Apache/Nginx and any PHP-FPM logs you need. What I expect from you 1. Identify the exact reason the login request is returning HTTP 500. Typical culprits might be fatal errors, missing includes, failed MySQL queries, or session permission issues—track down whichever one it is in this case. 2. Apply a clean, well-documented fix so the login redirects smoothly to the dashboard and no 500 errors appear. 3. Provide a short note that lists the root cause and the files or settings you changed so I have a record for future maintenance. Skills that will be handy: strong PHP debugging, MySQL, session handling, cPanel/Apache/Nginx administration, and familiarity with version compatibility pitfalls between PHP 7.4 and 8.x. Once the error is gone and users can sign in normally, the job is done.
