The scan runs before anything changes, and reports how many tabs are not currently reaching your product pages.
Tabsmith adds your own tabs to WooCommerce product pages: shipping information, care instructions, sizing, warranty, anything your customers ask about twice a week.
If you are moving from Custom Product Tabs (YIKES), Tabsmith reads your existing tabs and brings them across in one click – including any that were never reaching your customers.
WooCommerce identifies every product tab by a key. That key is built from the tab’s title. Two tabs with the same title produce the same key, and when that happens the second tab replaces the first. The first one is still saved in your database. It simply never renders.
This is easy to do by accident. A shop with “Shipping” on a product and a second “Shipping” tab added later has one tab quietly missing, with no warning anywhere in the admin.
Tabsmith scans for this before it changes anything, and tells you exactly what it found:
3 tabs across 1 product. 1 of them is not currently shown on your product pages.
Importing gives every tab its own key, so all of them appear.
Tabsmith formats tab content the way WordPress formats post content by default: paragraphs, smart quotes and shortcodes.
It does this without running the the_content filter, so page builders such as Divi, Elementor and WPBakery do not add their own layout inside your tabs.
Bug reports and compatibility problems get answered in the support forum. It helps if you include your WordPress and WooCommerce versions, your theme, and what you expected to happen instead.
Tabsmith is built and maintained by one developer, so I cannot take on theme customisation or bespoke development. Anything that looks like a fault in the plugin is worth reporting though – I would rather hear about it than not.
