Good to know

  • Wix only runs custom code on a published site with a connected domain, which needs a Premium plan.
  • If you connect a different domain later, Wix deletes your custom code. Add the line again afterwards.
  • Wix has tightened security on custom code since December 2025. After adding the line, check it works with the setup check.

Based on Wix's own help pages: Wix: embed custom code. Menus change from time to time; if something looks different, their help pages have the latest.
