My WooCommerce store at www.vilabijou.com needs three quick but critical improvements: 1. Upgrade the hosting environment to PHP 8.3. Please handle the full process—compatibility check, update, and post-upgrade testing—so the shop keeps running smoothly. 2. Detect every WooCommerce-recommended PHP extension and install whatever is missing. I’m not sure which modules are absent, so rely on the WooCommerce → Status report (and any other best-practice tools) to confirm essentials such as cURL, mbstring, GD Library and any others the platform flags. 3. Add a DMARC record for the same domain. Set up an aligned SPF/DKIM configuration if it isn’t already present, publish the DMARC TXT entry, and verify delivery with an external checker so we can track abuse reports confidently. Deliverables are simple: • Live store reporting PHP 8.3 with no errors • WooCommerce Status page completely green for required modules • DMARC, SPF and DKIM passing checks on tools like MXToolbox or Google Postmaster Please let me know your expected downtime (if any) and how soon you can begin.
