Hey Chauntelle,
Thanks for reaching out to us!
I’d be happy to help you out! To start, was this the specific snippet that you added to your theme’s functions.php file https://theeventscalendar.com/knowledgebase/configuring-eventbrite-tickets-to-use-eventbrite-co-uk/?.
If so, it looks like there may have been some changes in the Eventbrite API that we’ll need to go back and address in that tutorial. In the meantime, does the event import if you replace the previous snippet with the following http://pastebin.com/A9X9K9gg (updating for your domain structure)?
Let me know if this helps.
Thanks!
