This plugin works great. Simple and easy to install however, there some issues that I would like to point out. There are times that the plugin will output "Cannot use WP_array" or whateversoever in some point of the month /week. As a programmer myself, I think this has to be something with Instagram server communication that cause an error because it just gone after a few minutes. Probably because of request traffic. Another thing, the description control does not coresspond on what I had set in admin panel because the programmer forgot to put double quote on his code. "ture" instead of true in bollean comparison. Though these are minor concern, but it would best if the programmer take a look on this issue.
Overall, I would recommend others to use this plugin. Great Job!
