I’m running a website built from a CodeCanyon script and the user login / signup feature has suddenly stopped working. The form submits, but the expected action doesn’t complete, so new and returning users can’t get into their accounts. Here’s what I need: • Diagnose the root cause of the broken login / signup flow. • Apply a clean, minimal fix that restores normal functionality without disrupting other parts of the script. • Test the solution on both desktop and mobile to confirm users can register, log in, and stay authenticated. The site is live, so I’ll provide immediate access to the codebase and hosting panel. Please be comfortable working with typical CodeCanyon stack components (PHP, MySQL, JavaScript) and documenting any changes so I can re-apply them on staging or future updates. I’m after a quick turnaround—once everything is working again, a brief summary of what was fixed is all that’s needed.
