Translating a plugin

Problem:
On this site the WP Event Manager Plugin is used which creates a Custom post Type for events.

When trying to click an event in second language the events leads to a 404 - Content not found error, even if the event is translated to 100%.

Solution:
In this case the custom ost type slug ("event)" and the custom taxonomy ("events") slug and labels were not translated.

Translate the custom post type slug at:
WPML -> Settings -> Post Type Translation
and the custom taxonomy slug at:
WPML -> Taxonomy Translation.
