Shortcode/JS not working/showing on sidebar.

On my site, rebirthgaming.org, I am utilizing this plugin. I have created a widget for my sidebar (where it says Fly with us!) using the HTML plugin that this plugin recommends using, and tried both the shortcode and script. Neither of them seem to function.

I initially thought this may be due to my theme, however, if I click ‘preview’ in the widget creation in my dashboard for the HTM widget, it shows nothing for the js, and the shortcode preview shows literally just the shortcode itself. Neither preview shows what it should look like.

The preview, however, in the settings for this plugin itself, shows up correctly.

This plugin functions everywhere else, however, such as in the comments and on the default login splash for WordPress when trying to access my site, including the pop up that shows when you refresh the admin dashboard after logging out on another window/tab of my site.

It’s just the HTML sidebar widget that appears to not function.

I am using a custom icon set, however, I ensured they were named properly and their sizes are correct, so I do not think these custom icons should be causing the issue.

I ensured that my AdBlock is disabled for my site, as the plugin info indicated that it could possibly cause the icons to not show.
