is custom sidebar feature supported in WP 4.2.4?
I created the custom sidebar, but in no page or article i can change the default one, nor set Default sidebars for single entries. Where i read “There are no replaceable sidebars selected. You must select some of them in the form above to be able for replacing them in all the post type entries.” i simply see no “from above”.
could you please try visiting the “Appearance -> Custom Sidebars” admin menu item and selecting one or more sidebars in the “Replaceable Sidebars” section on the left side of the screen, then pressing the blue “Save changes” button in that section. Let me know if custom sidebars still do not appear after this manipulation!
