sidebar choice not saved for pages (but saved ok for posts/custom posts)
Strange problem (WordPress 6.1, PHP 8.0.25):
I created a new sidebar using the Appearance -> Multiple sidebars menu.
The new sidebar appears in the selection list in the “Sidebar” section of any page and can be selected instead of “Default Sidebar”.
However after saving that page, the selection list shows again “Default Sidebar”.
This strange behaviour is only for pages; any post or custom post remembers my sidebar choice (and shows the new sidebar).
I tried using an addon too (Custom Sidebars by WebFactory), same behavior (except that addon allowed an workaround of replacing the Blog sidebar with my sidebar, but I wouldnt use an addon only to fix something that should work).
Tried choosing all other page templates in the theme (EcoWorld by Softwebmedia), tried changing content layout to show sidebar left/right, making the selection for new pages vs. existent ones, no difference…
