Infinite loading during checkout process on paypal

[filip_slatinac1]

Hi, E-commerce manager here. 

Sometimes when my clients try and checkout the checkout crashes, I've been able to reproduce the error but it only happens once in a while. Here are some of the error codes, would love some help in identifying what the issue is. It seems to have happened after Amasty did an update on their 1-page checkout. 

Here are some screen shots of the errors in the console and network... any ideas? 

Thanks, 
Filip

Hi @filip_slatinac1

It looks like that some of your js files not loaded properly on your page and returning 404 not found.

Please check once console to make sure when your checkout load properly, then i think there will not be any js error.

Are you on production mode?
