When I try to use your plugin I run into these following issues (I am entering the correct information):
API Error: Looking for a valid api key paired with a valid portalId OR just a valid access token -- found neither. (hapikey=null, access_token=null, portalId=null)
HubSpot for Gravity Forms - Invalid HubSpot credentials. Please provide valid HubSpot credentials. Plugin will not work correctly until valid credentials provided.
Can you please help?
