Broken

The developer works in v2 and it is even better.

You can tested in: Opening Hours 2.0 beta 1
https://www.jannikportz.de/2015/04/20/opening-hours-2-0-beta-please-test/
and if you like so much help to continue its development Plugin page, on the right side of the page you have the donation button.

Tested it…currently it doesn’t seem to work with “page builder”?
I was able to set up the opening hours and holidays but now can not edit the pages (it brings me not the page to edit but an interface of the opening hours)
