In your code you’re using this to register taxonomy:
register_taxonomy( 'events_category', array( 'events' ), $args );
So the taxonomy is called events_category.
And in get_terms you use events_categories.
Here’s the fixed getting terms part:
$terms = get_terms( array(
'taxonomy' => 'events_category',
'hide_empty' => false
) );
I just figured out a solution by myself. It seems that this particular code needs to be in the loop - So it works now, the OP Code is correct then...
events_category, so you need to use that in theget_terms– Antti Koskinen Commented Feb 18, 2019 at 16:36
