Fatal error: Call to a member function getElementsByTagName() on null in /home/keyboard2/www/opencart-2_3_0_2b/catalog/model/extension/shipping/ups.php on line 243 at Step 4 - Delivey Method
The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.
If you're using OpenCart 188.8.131.52, then that error looks to be referencing this line:
Code: Select all
$response = $rating_service_selection_response->getElementsByTagName('Response')->item(0);
The error is saying that $rating_service_selection_response is null, which means there is no response from UPS. I don't think there are any bugs in UPS in 2.3, so you probably don't have it set up right. Double-check all your settings, and try playing around with some of them to see if you can figure out which one is causing the issue. You might also turn on Debug mode, to record what the API requests/responses are.
