Run a scan

Open WooCommerce → Product Data Checks and press Scan now.

The scan runs in the background in batches, so a large catalogue does not tie up a page load. Reload the screen to see progress. It reports how many products it has checked so far, and the time of the last completed scan.

If a scan appears stuck, Restart scan starts a fresh one.

What a scan looks at

Every published product and variation, except the ones that are never handed to a carrier:

• External and affiliate products, which are bought somewhere else.
• Grouped products, which are containers rather than things.
• Variable parents, whose variations are checked instead.

That last one matters more than it sounds. A variable product’s weight is only a fallback for variations that do not set their own, so the plugin checks the variations and reports the parent only when nothing is inheritable.

What a scan changes

Nothing about your products. A scan only reads.

It does update the findings list: a problem that has been fixed disappears, and a problem that has come back keeps its original First seen date, so it is shown as a regression rather than as a new finding. Dismissals are never undone by a scan. The scan decides whether a fault is still there, not whether you care about it.
