Well, I'm trying to install Ajax Quick Checkout FREE in my opencart 3.0 store, and I'm having the following problem, see if you can help me:
The installation runs normally, I go to the front-end mode and test Ajax Quick Checkout if I try to make the purchase without creating an account, it works perfectly, but if I go to create account it generates the account but not the sale!
And it only returns the following error:
Uncaught TypeError: Cannot read property 'length' of null
at Object.validate (d_quickcheckout.min.js:295)
at Object._validate (backbone-min.js:1)
at Object.set (backbone-min.js:1)

at l (backbone-min.js:1)

Image not to create account: WORKS

What could be happening?
Thank you!
