Hi AMGill,
First of all, sorry for my late response – I will do my best to help you with this issue. The error is internal, so it is not easy to debug – it can be caused by another plugin or misconfiguration of the server. Without having access to server logs, it is hard to tell.
Could you please send us the support request directly from your admin dashboard? You can do that by going to Eventbrite Events → Contact Us, and filling the form there. This will allow us to have a private conversation about this matter.
If you can provide us with the login details and FTP access to your website, we will be able to debug the issue. If, for some reason, it is not possible, please ask your developer/hosting support to provide you with the error log. The information on what is causing the issue should be there.
I appreciate your cooperation and I will be waiting for your support request! ??
