One-Page Checkout [Support Thread]

[lat9]

What happens if you temporarily change your template to the built-in responsive_classic? Does it display the same behavior?

Just trying to see if it could be a template-related issue.

I get the same Whoops timeout message

I get the same Whoops timeout message

OK, that weeds out the possibility of the template. What other plugins or changes have been installed/made to the site?

The issue that you're having has to do with the site's session creation/maintenance. Who's your webhost and what version of PHP is in use?

I'm following up on a post from several weeks ago. Client just approved installing the current version. I have 2.3.8 installed and getting the same error I was before when clicking update for the address section in guest checkout:

I did copy the one extra file in /includes/modules/pages/checkout_payment to /includes/modules/pages/checkout_one. It was: jscript_double_submit.php

You need to upgrade to a now-extant version of jQuery. Current version is 3.6.0; zc157c ships with 3.5.1.

We had tried that when OPC was 2.3.4 and still got this error. I've updated the site to 3.5.1 and get the same error:

Just noticed I'm using the minified. Do you need the unminified to get the right line numbers?

Yes, unminified version will pinpoint where the issue is sourced.
