Hi @jathinhelp, this answer does not help me as the problem only occurs with Polylang and multiple languages enabled (see problem description). I already opened a topic in the Connect Polylang for Elementor support forum, however as i cannot know which of the two plugins is causing the error here, i did post it here, too.
I am pretty sure in fact this is more of a bug than a support case, so i would be pleased if some core dev of WP Event Manager would take notice of it.
