1 Flash Gallery Plugin Doesnt Work With Some Browsers

Hi,
I am using 1 Flash Gallery Plugin and simply adore it. It is perfect for me. However, lately it was brought to my attention that It only works with some browsers.
It works with:
Firefox and Google Chrome
It doesn’t work with:
Safari and Opera

The problem is that it wont show all the pictures sometimes it will only show one picture or won’t load at all.

The site is https://itsawanderfullife.com/

Thank you so much for your help!
I’d like to fix this as soon as possible so please any answer would be helpful. (I am using the build theme)

I have not been able to test Internet Explorer yet
