Welcome to 2020. This year, we have BSIDESROC coming up in late March and, with a few of us hoping to compete and learn, I’ve adjusted my hacking kit and tools a little for this.

After hours of google searching with people saying anything from disabling plugins (there were none) to reverting settings (it was a NEW site with no posts prior to changes), this is the ONLY way I’ve gotten the custom WordPress Permalinks to work in the manner I wanted. Hopefully this saves others time/frustration.
