10Web Photo Gallery broken when using WP Bootstrap Starter theme

I am trying to install a new plugin to present photos in an album and after a lot of research I chose 10Web’s product (Photo Gallery) as it has all the features I want plus 4 other plugins (mailchimp, formmaker etc) and the paid version is a good value. After speaking to their support we found out that the Gallery is not working because of an incompatibility with the WP Bootstrap theme. I was asked to run the ‘Health Check & Troubleshooting’ plugin and then go to activate it and then go to the plugin and select ‘Troubleshoot’.  Then make sure that I select install latest theme and enable all plugins from inside the troubleshooting tool and then change between themes,  It looks like the Kadence and Twenty Twenty Four themese allow the Gallery to function with no problem but my WP Bootstrap Starter theme which is the one my website is built on is causing the plugin to break.  Go to this URL and test: https://staging.tridentwarriors.org/bwg_gallery/egypt-2022/ and then see the page here.

Now using the WP Bootstrap theme it is broken

Can you please help me to find out what the problem is?
