Hey Christina,
Please accept our sincere apologies for the delayed response! Can you please verify if the issue persists if you disable all of your plugins except The Events Calendar and The Events Calendar Pro?
I’ve just accessed your home page and that JavaScript error is still in place, but your images are displaying properly, so I don’t believe it is associated with the issue you are experiencing.
Can you please enable WP_DEBUG and WP_DEBUG_LOG and share with us any messages you see while accessing your home page and some of your events? All WP_DEBUG messages will be stored in a debug.log file in /wp-content/debug.log.
If you have any other relevant information to share about this issue, please let us know.
Regards,
Patricia
