Fix WooCommerce Merchant Feed

My WooCommerce store relies on the official Google for WooCommerce plugin to stream products into Google Merchant Center, yet the automatic feed has stalled—new items never reach Merchant Center and some older listings have disappeared completely. The connection itself is still live (the plugin is supposed to push changes automatically), but Google’s dashboard shows no recent updates, so the Shopping ads sit empty.

Here is what I need:

• Diagnose the root cause that prevents the Google for WooCommerce plugin from refreshing the feed.
• Restore a fully-functioning, real-time sync so every product, price, stock level, and image in WooCommerce matches Merchant Center without manual uploads.
• Re-submit the repaired feed, clear any residual errors, and confirm all SKUs are approved and visible.
• Provide a concise hand-over note outlining the fix and any settings, cron jobs, or API credentials you adjusted.

Acceptance criteria:
– Merchant Center fetches run on schedule and display a “Success” status.
– All active SKUs in WooCommerce appear in Merchant Center with accurate availability and pricing.
– No “missing feed” or “item not inserted” warnings remain after 48 hours.

You will receive temporary admin access to both WordPress and Merchant Center as soon as we start. If additional server-side tweaks (e.g., cron, caching, or PHP settings) are required, I can supply cPanel or SSH access on request.
