The way the plugin works, it hooks your content and detects your terms based on an array of all your published terms generated and updated when you add and update terms.
when it finds a term it encapsulates them in a way it is easy for jquery to find them.
The link or modal is generated in front in js based on the “mywpglossary_insertion_style” hook value ( ‘link’, ‘popin’ or ‘tippy_poppin ).
What you see is the unmodified encapsulation of terms, and certainly a js errors prevent the script to do this work.
I cannot promise anything, but maybe I can find some time to work on this this weekend.
I really appreciate your enthusiasm for our plugin, Thank you.
https://unpkg.com/ is a public repository of javascript library, it’s used when you don’t or can’t want to redistribute lib in your production. Glossary load tippy ( https://atomiks.github.io/tippyjs/ ) a pretty nice popup lib. And tippy is based on popper( https://popper.js.org/ ) so it loads some files from it.
A map file like this is used as a translation layer for the minified version of the script, it has only use in a development or debugging context. It seems from your logs and the link, the map file for the last version of popper is missing. Not a big deal as this url is reserved for the last stable version and will probably be fixed at some point.
Best regard.
