lfh is not defined

Hi

I’m trying to use this plugin in a WP 4.9.8 with thois shortcode :

[lfh-gpx src=”https://www.ato-photos.com/gpx/islande/de-skogafoss-a-baldvinsskali.gpx” color=darkgreen width=6]De Skógafoss à Baldvinsskáli[/lfh-gpx]

And on the portfolio page I only have a blank square : https://www.ato-photos.com/photos/islande-episode-1-le-jour-le-plus-long/

In browser console there is this error :

ReferenceError: lfh is not defined[En savoir plus] lfh-front-min.1.12.0.js:1:1857
