Hi Luca,
Thank you for your interest in your plugins!
In order to set up a multilingual website with The Events Calendar, you would need to activate a multilingual plugin as well, such as the well-established WPML plugin.
Here, you will find a guide to set up The Events Calendar and Events Calendar PRO with WPML. We also support compatibility for theĀ Filter Bar add-on.
While we strive to be compatible with WPML and invest considerably in this effort, we can not guarantee 100% compatibility (as is true of third party plugins generally). Some of our add-ons are not currently supported or compatible with WPML, including Community Events.
If you have any further questions, please don’t hesitate to contact me.
Cheers,
Jeremy
