I thought this plugin was great. After editing some lines in woosidebars I thought I broke something, for over an hour. When saving changes to the woosidebar widget area (which is posttype sidebar) it is MOVED to a regular post type (post) with all settings gone. tried changing it back in db didn't work either. All settings are gone and sidebar is now a blank post.
After removing and reinstalling woosidebars and activating/deactivating Post Type Switcher found the problem is Post Type Switcher. it breaks any plugin using its own posttype.
