Can’t open builder

Hi,

Your plugin sounds like it will make my life wonderful again but unfortunately, I can’t get the builder to work. It opens my product page but there is a javascript error in the console. The various features for configuring fields I see in your video do not appear.

Uncaught TypeError: Cannot read property ‘replace’ of undefined
at Function.m.template (underscore.min.js?ver=1.8.3:5)
at builder.js?ver=4.0.11:1624
at builder.js?ver=4.0.11:3884

Please let me know an email to send credentials to if needed.

Thanks! I hope we can get this working!
