No event content showing on localhost sites

I am able to display events via Eventbrite API on live sites, but not on my local development server, on localhost (on Windows PC). Using a hack (using the oauth uri of https://localhost/trunk/src/wp-admin/tools.php?page=keyring&action=verify&service=eventbrite instead of the suggested oauth uri in the set-up process) I am able to get a listing of the events on the designated page, but each entry is blank (no content, no associated image). I’ve tried this on several localhost sites just incase the issue was with a theme, which it didn’t seem to be.

The console is showing an error message of ‘Refused to display ‘https://www.eventbrite.com/tickets-external?eid={eventnumberhere}&ref=etckt’ in a frame because it set ‘X-Frame-Options’ to ‘SAMEORIGIN’.

So I understand there seems to be an issue with localhost and X-frames. I’m not sure which end this is at, nor how to change it.

If anyone has a suggestion please let me know. Thanks!
