Site Inspector troubleshooting

Chrome blocks extensions from browser-internal pages — chrome://, chrome-extension://, the Web Store, and the new-tab page. Open any normal website and the panel works. This is a Chrome platform restriction, not a bug.

Expected. The breakpoint previewer and the Tags tab's live event monitor both use Chrome's debugger API — the yellow banner is Chrome telling you it's attached. It disappears when you stop monitoring / exit the breakpoint preview. Both tools share one attachment, so they can run at the same time.

The monitor only captures hits fired after it starts — reload the page once monitoring is onto catch the initial PageView and page-load events. If it's still quiet, check the Detected tags section: a page with no Google/Meta tags installed has nothing to fire.

All DOM-mutating tools inject a tagged style element and revert by removing it — but if something looks stuck, refresh the tab: every change the extension makes lives only in the current page state and a reload fully resets it. Nothing is ever written to the site itself.

Usually duplicate element IDs — page builders like Elementor render the same form more than once (responsive copies, popups), and a naive selector grabs the hidden empty copy. Generated scripts now scan every element matching the selector and use the first one that actually holds a value; re-generate the variable from the Fields tab if you created it on an older version.

The scan covers active ads only(paused and archived ads are skipped) and reads the creative's creative_features_specvia the Marketing API. Meta's API names differ from the Ads Manager UI — the checklist shows the friendly label with the raw API key beside it, so double-check you're comparing the same feature. Placement tags and settings like hide_price are intentionally excluded from auto-disable.
