Quick WordPress Bug Fixes

My live WordPress site is throwing intermittent error messages and a couple of plugins have started clashing, breaking key features. I need those issues traced and eliminated so the site loads cleanly and stays fully responsive on all devices.

The core priorities are:
• Remove every visible error message and any underlying PHP, JS, or database warnings they stem from.
• Hunt down the plugin conflicts, adjust settings or code as needed, and confirm all active plugins coexist without warnings.
• Test and prove that every form submission reaches the correct inbox or database entry.
• Run through the e-commerce flow—product pages, cart, checkout, payment gateway—to be sure customers experience zero glitches from browse to receipt.
• Double-check mobile and tablet breakpoints so styling and layout remain intact once the bugs are gone.

Clear, prompt communication is essential: keep me posted on findings, fixes applied, and any follow-up steps I might need to take. The work must be wrapped up within the timeframe we agree on, and the site should come back to me clean, fast, and stable.
