Hello…have you set up a client? If yes…is it an unused and new client dedicated just to instagrabber? If you’re copying/pasting the client ID and client secret double check that there isn’t a space in front of after the cut and paste. This is what happened to me.
This is the first I’ve used wordpress and I’m still getting familiar with how to get things working. How do I set up a client? I don’t think I’ve done so. I have an instagram and used the log in info for my instagram.
You don’t have to setup a client.
Choose “Instagram Authorization type”: Instagrabber
