Wix Product Configurator Stops Working

This is so frustrating, and costing me potentially missing out on sales!

I set up a custom product configurator, which I love by the way, and was one of the reasons I chose Wix to host my site.

I noticed recently through Google analytics that I am not getting any cart visits - odd I thought. I decided to check my site and the product configurator stopped working!!

I have not even logged in to Wix to edit my site so this is not something I have done!

This is the second time it has happened - I initially thought it was something I had done, so completely rebuilt the configurator to get it working, but this second time is no coincidence!

The weirdest thing is when I go to my site editor it still works in preview, but not on the live site!
