Error: Cannot add access token directly to the shortcode.
Due to recent Instagram platform changes, it's no longer possible to create a feed by adding the access token to the shortcode. Remove the access token from the shortcode and connect an account on the plugin Settings page instead.
Error: Access Token for benangmerah_portfolio is not valid or has expired. Feed will not update.
There's an issue with the Instagram Access Token that you are using. Please obtain a new Access Token on the plugin's Settings page.
