Default UPS extension crashes checkout a step 2

[timlight10]

Hi there,
Users are reporting that when they get to checkout step 2, they get back a blank page.
In my error log I see this:

Code Select Expand

2025-10-05 8:51:16 - Unknown Error: AbanteCart core v.1.3.4 Call to a member function getElementsByTagName() on null in <b>/public_html/dps/extensions/default_ups/storefront/model/extension/default_ups.php</b> on line <b>462</b>Disabling the default UPS module allows checkouts to continue.
Any advice?

Hello.

Version 1.3.4 is quite outdated. It is recommended to make a full backup of your database and files, then update to the latest AbanteCart release. This should resolve the issue with the UPS extension and ensure you get all recent fixes and improvements.
