Hello, trying to figure this one out.
I wanted to change the structure of my permalinks and install 301 redirection for internal linking, when I click on permalinks inside WP, all seems to work fine except that I can’t see anything, all I get is the default WP gray background, no errors, no nothing.
I’ve disabled all plugins, no change.
I’ve changed back to default theme, no change.
Don’t know what else to do.
