Hey Holly,
Sorry about your troubles here! Let’s get to troubleshooting this promptly.
First on the list of things to investigate is your site itself, obviously, but when I went to the domain name you provided (http://www.xisleparty.com/), I can’t connect to the page at all. (Screenshot → https://cloudup.com/cZh03dbQZ4N)
Next, can you address of the following points in order?
1. What version of WordPress is running on your site?
2. What version of The Events Calendar is running on your site?
3. What version of WooCommerce is running on your site?
4. What version of WooCommerce Tickets is running on your site?
Thank you!
George
