Ever thought about to use your (remote) CalDav Calendar(s) as an automatic data source for your favourite WP Calendar Plugin ? 
Searched for a Plugin that would provide this functionality in the WP Plugins Directory and found nothing useful ? 
Well, in case of ‘Yes’ to both questions, this is for You 🙂 . 
Just read the whole story at https://hoernerfranzracing.de/werner/kde-linux-web/wp-caldav2ics to check out if this will fit your needs… 
And yes, Calendar(s) is correct from Version 1.1.0 – you are no longer limited to just ONE Calendar Source !
