Greetings, reftagger works with WIX! and it a very simple solution.
1. Log into your WIX account. Open another browser with https://faithlife.com/products/reftagger
2. Copy the code from https://faithlife.com/products/reftagger
3. Go to your WIX dashboard, on the left-hand side scroll down to "settings" click that.
4. scroll down to "advanced" then over to the right "custom code" click that.
5. scroll down to "Body End" then paste the reftagger code there (note be sure to set of the version, and design in reftagger before you copy the code) then paste the code.
6. Hit "save" or "apply"
7. Go to your pages that you have verses on and hit "save" and "publish" (I do that just as added saving)
8. Go to your site "live" and test it. For me, it works but I noticed I had to refresh the page to get it to work. And I checked on mobile and it works too!
Let me know how it works for you!
Jesus Bless you all.
