Conflict Polylang Events Manager

OK, after some testing I see that the problem is with the language code, links from Calender widget are linking to events page with the /lang/ prefix, it shows as 404 error.
https://site-domain/en/events/2013-06-03/ – 404,
https://site-domain/events/2013-06-03/ – everything is fine.

Is it Polylang or Events Manager bug?

It’s not because two plugins are not compatible that there are bugs. It may be just because they are not aware of each other.

For your information, there is a plugin to make WPML and Events Manager (not fully) compatibles. It is approximately 600 lines of code. I am not ready to make such investment to make Polylang support Events Manager.
