Este plugin no se ha probado con las últimas 3 versiones mayores de WordPress. Puede que ya no tenga soporte ni lo mantenga nadie, o puede que tenga problemas de compatibilidad cuando se usa con las versiones más recientes de WordPress.
I just gave this one a test after responding to someone else having issue with another similar plugin. I might actually make use of this one myself as the one I was using (Display Categories Widget) is all messed up with our new theme.
if they could add a radio button to select either include or exclude it would be even better. I use categories to archive stuff that i don't want to show on the main page so including just my main categories is easier than having to add the new archive cat to the exclude list.
Installed a week ago and the plugin hides a single category as expected. However, I just added a second category to hide, but it is not working. Hopefully an easy fix -- I've submitted a support ticket. Great plugin -- just need to get it to work properly.
