Why am I seeing an Invalid WSDL file at domain message when integrating with Magento?
When trying to add integration from Klaviyo (Magento ver. 1.14.4.1), receive the following message:
Invalid WSDL file at https://www.mydomain.com. Received error message: "<unknown>:1:0: no element found." Please contact support or forward this error to your technical team.)

Any ideas?
