I will fix one JavaScript or PHP website bug with proof

I will troubleshoot and fix one clear JavaScript or PHP issue on an existing website or small web app.

Good fit:
- broken button, menu, modal, form, or script behavior
- PHP warning, small template issue, or simple backend error
- browser console errors
- small WordPress, WooCommerce, or custom theme issue
- one reproducible bug with a clear before/after check

Deliverable:
- fixed file or patch notes
- before/after screenshot or short screen recording when useful
- short explanation of the cause and what changed

I need the page URL, steps to reproduce the bug, expected behavior, access details if required, and permission to edit the relevant files.
