@morgler Sorry, but this is not a good approach as a WordPress user
Please never jump straight to a 1-star review without asking for help.
Inside the plugin there’s a box pointing you exactly where to go for help: “If you need help or have a new feature request, let us know.”: https://imgur.com/a/oqG2uzk
Here’s where that link goes to: https://wordpress.org/support/plugin/organize-series/
Please remove this review and ask for help instead.
@morgler Matthias, thanks for updating the review, but now we’re off onto a completely different topic.
Please just post a support question first!
If you have installation questions, URL questions, CSS styling questions … whatever it is … please just ask, and you’ll get help.
