Fixer Theme: Short Code for Plugin no longer displaying gallery correctly after update

Hi there, this site has a plugin that allows the owner to add a gallery to a page via a shortcode [bwcgallery] - however, no matter if I add it via text, code, etc. the gallery either doesn't show up at all or it shows up with the images aligning vertically. The images should align horizontally.

We have tested the plugin on other sites with other themes and the issues seems to be with the theme. The plugin is working fine. Can you help me?

I've also attached some screenshots and granted support access :slight_smile:
