Hello, the plugin works well on localhost, but when it goes up on the server, the thumbnails don’t appear, and it shows only the caption. In the Chrome element inspector, it shows the following error message:

Failed to load resource: net :: ERR_BLOCKED_BY_RESPONSE

As many as this kind of plugins it shows error on CORS policy.
How can it be fixed?
Thanks

Hello and thank you for this plugin!
There is tiny little bug:
line 90 should be deleted:
$simple_social_feed_html .= '</div>';
or
line 70:
$simple_social_feed_html = '<div id="simple-social-feed-'.$random_string.'" class="simple-social-feed-container instagram_feed"></div>';
just remove closing “</div>”
I am right?

Hello.
How can I remove the distance between photos in the feed?
Thanks in advance for your answer.
