Hi
I am using Easyship extension for magento 1.9.3.1 version. I have setup REST API configuration as per extension but still I can not Active extension. When I request for API "https://api.easyship.com/api/v1/magento/registrations" its showing "Invalid header line detected" in response.
Please help me so can active extension from admin.
