The "thing" is that the billing address is always required, but the shipping address (think 'virtual products') isn't. That's why the billing address is displayed first.

1. OPC makes those AJAX calls to ensure that any time-based (think UPS Early Morning) methods are 'proper'. If a customer has sat on the page for a couple of minutes just prior to the Early Morning...

I've just submitted v1.7.10 of the UPSXML shipping method for the Zen Cart moderators' review and will post back here when it's available for download.

This release corrects a PHP 8.0+ Fatal...

... but someone else has, and there's a fatal error due to the fact that the XMLParser class is now in the PHP base. See https://github.com/lat9/upsxml/issues/27; v1.7.10 forthcoming.

There's also the URL Redirection Manager (https://www.zen-cart.com/downloads.php?do=file&id=2152) which, IIRC, needs some work to run under current (i.e. 7.4 and above) versions of PHP, but it might...

Since the site is running https-all-the-time, your site's root .htaccess file should 'support' that. Make a backup copy and add the following clauses close to the top of the file to 'force' the...

Are you using an "URL Mangler", e.g. Ceon URI Mappings or Ultimate SEO URLs?

In addition, check your storefront /includes/configure.php file to make sure that both the HTTP_SERVER and HTTPS_SERVER definitions start with 'https' and that ENABLE_SSL is set to 'true' (including...

I appreciate the posting. The readme for v2.4.1 will be updated to be more generic in its instructions!

Both the USPS and FedEx shipping methods 'pull' their quotes from the shipping 'supplier'. Depending on how busy the usps and/or fedex sites are, that's where the delay is coming from.

See https://github.com/lat9/one_page_checkout/issues/328 for the resolution to this issue.

Thanks for the report, @swguy. That issue arises when the site has Configuration :: One-Page Checkout Settings :: Enable Shipping=Billing? set to 'true'. GitHub issue forthcoming.

GitHub issue...

Noting that you could create a template-override of /includes/languages/english/checkout_one.php (i.e. /includes/languages/english/YOUR_TEMPLATE/checkout_one.php) and update the...

I'd forgotten about this one! I've not installed it with zc157, but as long as you're using a version other than the original (zc157, which had issues with multiple observers), it should be just...

While I'm not convinced that a 'simple' move from PHP 5.4 to 7 and back would have any affect on the site's /includes/configure.php file, that's where the database settings are "registered" for use. ...

What version of PHP and Zen Cart? What payment and shipping methods are installed?

Are there any redirects present in the site's root/.htaccess file?

niccol, you've got the correct zc157 version; my initial response was my foobar.

GitHub tracking issue: https://github.com/lat9/one_page_checkout/issues/326

@niccol, what version of Zen Cart are you running on? The zc157+ version of /includes/classes/message_stack.php don't include that session reset.

Update: Never mind; I'll get OPC updated.

Please take the OPC issue over to its support-thread. You'll need to identify what template is in use and note that zc156 is fairly old.

@dbltoe, what happens if you change line 567 of /includes/classes/OnePageCheckout.php from


$this->debugMessage('startGuestOnePageCheckout, exit: sendto: ' . ((isset($_SESSION['sendto']))...

Zen Cart version?

Different error log, but the same underlying root-cause: The customers_info table is (I'm guessing) one record bigger than the customers table itself.

What's the largest customers_id value present...

That's very strange, since the processing in that section of paypalwpp is creating a new customer and using the unique '$customer_id' associated with that just-created customers table for use in the...

What is the site's setting for Configuration :: New Listing :: Display Product Date Added?

Sounds like a great idea, @marcopolo; see https://github.com/lat9/access_blocker/issues/13 for tracking.

You are seeing a "partial whitescreen"; check the site's /logs directory for a .log file that identifies the cause.

Absolutely not! :no: You'll need to perform a file-compare (using a program like WinMerge or Beyond Compare) to merge the MAP changes into that updated version.

@giancalr, I'm sure that it's possible but I'm not sure how at the moment.

I've just submitted v2.4.0 of One-Page Checkout for the Zen Cart moderators' review; I'll post back here when it's available for download.

I've just submitted v2.2.1 of Super Globals Plus for the Zen Cart moderators' review; I'll post back here when it's available for download.

This version corrects a PHP Fatal Error when running...

FWIW, the correction for zc158 was to remove that offending section; see https://github.com/zencart/zencart/commit/e901460bd1417e5b69c96cf5acb4d5b6c69dd3cf

Since you didn't indicate which variant of PayPal is being used, I'm guessing paypalwpp (PayPal Express Checkout). If that's the case, edit /includes/modules/payment/paypalwpp.php, finding this...

The files in the /extra_configures and /extra_datafiles directories are loaded way-early in a page's load and, specifically, prior to the session being started. You could add that code as a...

Which variant of PayPal? Noting that for PayPal Express Checkout, there's a setting (Transaction Currency) that should be set to USD Only for the use-case you've presented.

Noting, too, that there's a change in the zc158 branch that enables these settings to be 'controlled' without core-file-carving:

OPC is not stripping anything ... but one of your order-totals might be. OPC goes off a hash of the session, checking that nothing's changed since the customer indicated that the order is to be...

I'll note that the 'displayed' version has a trailing colon (:).

What are the before and after values?

A screenshot's better, since that's got the styling that identifies the differences.

You don't want (or need) that closing ?> ... it can cause issues if there are spaces or new-lines after it, resulting in "Headers already sent" type issues.
