Created four new galleries for my website.  Used the Juicebox Builder.  Locally all four work when uploaded three show up as white pages and the fourth works fine.
When using Firefox and the console view I can see on the 3 galleries that show up as white.  Have an error saying that the script "http ://******/jbcore/juicebox.js" was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.
Then have Loading failed for the <script> with the source "http ://******/jbcore/juicebox.js"

Have tried copying the juicebox.js file from the gallery that works and still get the error.
Tried viewing on Firefox, Edge and Chrome.

Could understand having either all working or all not working but 1 out of 4 working has me confused. 

Juicebox Pro V1.5.1 and latest version of Adobe Air.
