Checkout Issue in PrestaShop: Correcting Form Data Blocks Progress to Next Steps

[p.Góra]

I'm having trouble with the latest PrestaShop 1.7.8.10 in the purchasing process. I've never encountered something like this before. The issue is that during a purchase, if I enter information into the form fields and forget to fill in or incorrectly fill in a field in one of the sections, even after correcting it, clicking 'next' doesn't allow me to proceed to the next section.:( There are no JS errors in the console. If I enter correct data from the beginning, the form works fine. The error only occurs when there's a need to correct a field or fill in missing information. This issue is specific to the order checkout process in the store; everywhere else, it functions correctly.

I am asking for help and advice

Hi,

Clear your browser cache and try again, If that doesn't help, then start by checking your server error logs. Sometimes, issues that prevent form submissions can be related to server-side problems. Look for any PHP or database-related errors that might be causing this issue.

Thanks!

Thank you for the tip. Of course, I cleared the browser memory. It doesn't do anything.
I noticed that it blocks this piece of code:

function(t) {
return T.event.triggered !== t.type ? T.event.dispatch.apply(e, arguments) : void 0
}

But when I remove it, many other things in the store don't work, so it's not the direct cause.

And the whole thing looks like this:

Thank you again for your answer. I will try to look for an error in the server logs.
