Joe quickly helped me resolve this issue:
It’s most likely caused by differing versions of jQuery being enqueued between the theme and plugin. The fix: the plugin is designed to allow you to specify on which pages you want the jQuery to run.
In the plugin’s Behavior Editor there is a field that will only load the plugin’s jQuery for the page IDs specified.
Personally, I only needed the plugin’s jQuery to load on my site’s calendar page so I looked up that page’s specific ID.
I got my page ID through phpmyadmin. Alternatively you could install the “Reveal Id’s” plugin by Oliver Schl?be which will also show the ID.
Next, on the Behavior Editor screen for the My Calendar plugin, at the top the very first field is titled, “Insert scripts on these pages (comma separated post IDs)” and you put in the page ID there. This causes the javascript to be loaded no where else on your site except on the specified pages. Lightbox is back throughout the website!
Thanks Joe for all the help!
