hello, I moving my website from one folder to the root of the server and the plugin stopped calling instagram pictures.
before he was http://www.exemple.com / folder and now modified the index file to call "require (dirname (__ FILE__) '/folder/ wp-blog-header.php'.);" for your site to be seen at the address principal, after that the plugin stopped working.
I should not change the url of the redirection of the application:
sorry for my bad english.
