So I recently updated the permalink on one of my pages for indexing reasons. That same page has 3 child pages that I also updated and now all the child pages give me an error 404 when I try to load them.
The permalink is exactly what it should be and I publish it to match, it just give me an error though. Here's the specific change I made.
parent - foxvalleyphotoworks.com/portfolio/
child - foxvalleyphotoworks.com/portfolio/color
child - foxvalleyphotoworks.com/portfolio/black-white
child - foxvalleyphotoworks.com/portfolio/hdr
parent - foxvalleyphotoworks.com/gallery/ (works)
child - foxvalleyphotoworks.com/gallery/color (error 404)
child - foxvalleyphotoworks.com/gallery/black-white (error 404)
child - foxvalleyphotoworks.com/gallery/hdr (error 404)
