Fix AI Website Login Bugs

My AI-generated website is live but visitors get stuck at the very first hurdle: the sign-in form throws an “Invalid username or password” message every time, even when the credentials are correct. I need the authentication flow repaired so new and existing users can sign in smoothly, stay logged in, and move through the site without glitches.

While you are in the code, I’d also like a quick sweep for any other obvious bugs that might affect basic navigation or user actions so we can launch with confidence.

Deliverables
• Working login flow (sign-in, session persistence, sign-out) with the current “Invalid username or password” error resolved
• Brief summary of any additional bugs found and how you fixed them, committed to the repo

I’ll give you repo access and staging credentials as soon as we agree on the engagement.
