FedEx Module Problem

I found the cause of the issue, maybe this will help others.

When I set the Fed-Ex test account up, I used my home address. When i tested for quotes, I used my home address. Fed-Ex obviously will not ship something to yourself

I wrongly thought because Open Cart Fed-Ex plugin sent the store zip/state/country that Fed-ex used that. Fed-Ex will use the address in the account.

The changes to outlined in this topic all worked. TY

I'm experiencing the same thing. I can't save any Fedex services.

I have followed straightlight's instructions in this thread for corrections to fedex.twig and fedex.php. Both issues were found, corrected, uploaded. Installed as instructed, cleared cache, maintenance refresh. But I still have the issue as follows:

Warning: DOMDocument::loadXML(): Empty string supplied as input in /var/www/html/mysite/catalog/model/extension/shipping/fedex.php on line 164Notice: Trying to get property 'nodeValue' of non-object in /var/www/html/mysite/catalog/model/extension/shipping/fedex.php on line 170Notice: Trying to get property 'nodeValue' of non-object in /var/www/html/mysite/catalog/model/extension/shipping/fedex.php on line 170

These are two line of code:
line 164 from fedex.php is: $dom = new DOMDocument('1.0', 'UTF-8');
line 170 from fedex.php is: $this->log->write('FEDEX :: ' . $response);

and the follows is error log:
2020-10-09 18:08:17 - PHP Warning: DOMDocument::loadXML(): Empty string supplied as input in /var/www/html/mysite/catalog/model/extension/shipping/fedex.php on line 164

Any advice would be appreciated. Thank you!

Error says for itself: empty Fedex response, nothing to load and parse.
