Moodle: Javascript errors preventing SCORM package loading?

General information for the website: We deliver online training
Description of requirements/features: I'm having some issues on my Moodle site through which I provide online training. We upload SCORM packages to the Moodle and recently have had an issue which is stopping the SCORM packages from loading or sometimes just taking a very long time to load.

We receive the SCORM error that the "SCORM player has determined that your internet connection is unreliable or has been interrupted. If you continue in the SCORM activity, your progress may not be saved. You should exit the activity now and return when you have a dependable connection".

However, we have tried this from a number of different internet points and devices, with the same problem reoccurring. We therefore contacted our hosting provider, who replied:

"It appears the issue is coming from the fact that there are quite a few JavaScript errors on the site. I am pasting them below:

Can anyone assist and help me identify what the problem is that is causing the loading issues with my SCORM packages?
