WordPress QA & WooCommerce Bugfixing

My live WordPress site needs a thorough health-check followed by rapid fixes. I want every corner of the installation—theme, child theme tweaks, core files and the full WooCommerce stack—to run flawlessly, especially the payment gateway, which is mission-critical for me.

Here’s the exact flow I expect:

• Comprehensive desktop test across Google Chrome and Firefox (Safari could be a future phase).
• A concise, well-structured report that pinpoints each issue: broken links, layout glitches, slow queries, checkout errors—anything you uncover.
• Immediate resolution of every item in that report, with before/after notes so I can track what changed.
• Final confirmation that load times are competitive and that the storefront behaves perfectly on all common desktop resolutions.

Please be comfortable editing PHP, CSS, and JS inside child themes, debugging WooCommerce hooks, and optimising with standard tools such as Query Monitor, Lighthouse or GTmetrix. If you already use staging workflows, let me know; otherwise I’ll give you access to my staging sub-domain so production remains uninterrupted.

Deliverables that will signal a successful hand-off:
1. Issue log (spreadsheet or shared doc) with clear status for each item
2. Patched site pushed to live and re-tested
3. Short recommendations list for any future improvements you notice along the way

I’m looking to start as soon as you can confirm timing.
