Hello,
Could you tell us your version of PHP and also please make sure to use the latest version of EventON Lite?
Do you have the same issue with disabled third-party plugins and also switching the theme to the default one?

Thank you for your messages! I am going to contact @ashanjay about this. He’ll reply ASAP.
Please update to the latest version 2.4.9 — that will fix the issue for CSV not exporting events.

Thanks, it works.
I have some formatting issues with the export (shortcodes break the export formatting) but I will make a new ticket for it.
