I had a bunch of "Widget Areas" registered for my theme. I removed a few and added a few. The ones which I removed, I deleted the code which is hooked on
widgets_init for registering the sidebars. I have also "unregistered" the old "widget areas".
I've looked in the database, and see no references to these Widget Areas. However, for some reason, when I navigate to
WP ADMIN -> Appearance -> Widgets the old "Widget Areas" are still appearing, when they shouldn't be. The code which registers them has been removed, and they've already been "unregistered".
Is there some sort of cache for registered widget areas or something?
