I have been trying to get this to work for over an hour!
I have followed the instructions to the letter. I have added a new client, entered the data, into both wordpress and instagram. I enter my username and password, it redirects back to the settings... but no username!
I've checked and checked that there is 'http://www.' in front of the instragram redirect uri, and in the wordpress plugin settings and on my website general settings. Please help!
