Drupal 7.61 CiviCRM 5.4.1
When you click Edit or Change Billing on recurring donations, donors get "Network Error - Unable to Reach the Server"
I do get a console Error and a Warning.
Warning = jquery.min.js?pjxwd7:4 [Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check xhr.spec.whatwg.org.
