API Instagram

I’m French and I sell Instagram followers and likes. My website is: www.illowers.com. I need your help to solve a problem with the API instagram installed on my website. The Instagram API is used to check whether the usernames and the photos entered by clients are valid or not. It was set up by a former freelancer who doesn’t have time anymore to fix this problem. It is worth reminding that when he set up the API, everything worked perfectly. It hasn’t been working for five days now despite the fact that I didn’t change a thing. The API works perfectly for Instagram usernames (properly check if the username is valid or not). However, as far as the" Instagram Likes" are concerned, the API acts as a bug. Whatever you enter or upload, it says that the picture is not valid, even though you are positively certain of its validity. Can you fix this problem? Here are a few informations about the API: [login to view URL] Regards, Aurélien
