  • I had the same issue. My change was adding Google Tag Manager and Facebook Pixel. Having both up caused this error. Removed Facebook Pixel (single) and left the one I added to Google Tag manager.
  • You can download the "Facebook Pixel Helper" to help to debug: marketlytics.com/analytics-faq/…
  • Interesting how. As I was saying before, I tried running the code from the console on the page which is not containing that code (no facebook pixel on the page at all). Got the same result. I didn't duplicate anything. Facebook pixel helper says pixel loads fine, but the error keeps alerting. And yes, I'm 100% sure that there's no fbq('init', <pixel_id>) duplicate on the page. But thanks for the effort.
  • Running into this issue too and there isn't much to go on.
