Hi,
I tried both options you suggested, but the problem remains.
It’s very confusing not knowing what you have selected.
Hello,
Thanks for your help. Unfortunately, the problem remains. The “undefined offset” warning has gone, but the ordering does not work.
The drag n drop works fine, but after page refresh, nothing has changed. So I guess that has to do with the DB.
Just to note that I had installed the “Intuitive Custom Post Order” plugin, and after I removed it the WP Sort Order stopped working for custom taxonomy.
There is no plugin for custom taxonomy, it is registered in PHP code.
