I am using a theme from ThemeForest called Jardi Winery.
(https://themeforest.net/item/jardi-winery-vineyard-wine-shop-/16390279)
I have been using the Square plugin and everything was going fine until recently. I’m not sure when this started exactly however I am getting a similar error when Square is activated in Woocommerce. The page will not load and hangs.
(index):78 Uncaught ReferenceError: WC_Square_Payment_Form_Handler is not defined
at HTMLDocument.<anonymous> ((index):78)

at HTMLDocument.J (jquery.js?ver=1.12.4-wp:2)
So that the site staying working I have turned Square off and am using Paypal until this is fixed.
I have contacted the theme builder and they say it’s not their problem and to contact you, even though when temporarily testing with the 2020 theme i don’t get this issue.
The website this occurs on is http://www.bartonestate.com.au.
