some trouble with permalink?

hi,
normally when you address the slug permalink, like https://domain.com/knowledgebase, it must list the defined categories and belowehis post entries, that sometimes it work, but other not.

i couldn’t exactly determine when it doesn’t work, but it happened to me, after i rename, or re-create and/or re-assign another new categories.

i think this is also related to another questions in this support about ‘category widget’ that doesn’t work

also could it be if category name or slug is also used as article name or slug

regards, pescadito
