Hey Fabrice,
Thanks for reaching out.
I wasn’t able to reproduce any problems with that variable, so I’m wondering if you can clarify a things to help me investigate this issue:
1. Can you please post your site’s complete, un-edited system information? Here’s how to do that → https://theeventscalendar.com/knowledgebase/sharing-sys-info/
2. Next, can you please specify the exact file path to your customized template file where this problem arises? You mention “single-event.php” — but there are numerous instances of this file in our templating system. Is yours at [your-theme]/tribe-events/list/single-event.php, for example? Or perhaps [your-theme]/tribe-events/pro/map/single-event.php
3. Finally, can you copy and paste the complete, un-edited custom file you are referring to into a Gist at http://gist.github.com, and then share a link to that Gist in your reply?
Thanks Fabrice! With this extra information I’ll try to piece together exactly why that variable is blank for you.
Cheers,
George
