When trying to add the Upcoming Events widget in the WordPress customizer, it appears to add the widget on the preview screen, but I get an error saying "Invalid value." and nothing else. If I try to publish the page, I get an error "Unable to save due to 1 invalid setting". I'm using Version 1.3.13 of Calendar and WordPress 5.1.1. Otherwise Calendar is working. Any ideas?

For a page, you need to use shortcodes, such as

Code: Select all

[calendar type=”upcoming”]
For sidebars you can use the widget. I have both tested as working in WordPress 5.1

Try entering category IDs in the empty box there, just put them all in if you want all of them, like 1,2,3,4 etc.
