event calendar integration with WPLM plugin

Hi,

Once again great plugin and thanks for previous help. I’m going to switch to PRO version if I can figure out this last issue I’m having.

I have followed your tutorial on how to set up event calendar with WPML so I can translate event pages:
https://theeventscalendar.com/knowledgebase/setting-up-the-events-calendar-with-wpml/
However, every time I press save i get redirected to a blank page and my changes remain unsaved. I’ve tried deactivating all the other plugins and reinstalling WPML as well as Event calendar nothing seems to work.
