Out of nowhere juicebox now displays a error (Juicebox Error: Config file not found) and cant find any info in your forum or in google to help me and have no ideas where to go now. Using Pro vers 1.5.1 in Drupal 7 Any assistance in this matter is great appreciated!

You can see the error only on iOS on any guitar page on this url:
