According to other threads that are popping up, there was a site update that seems to be causing this. The game pages and the mods are still receiving the submissions, they just aren't appearing on the runner's page. No cause for alarm.

Yeah, I notticed that too. Will it get back to normal?

To seriously answer your question @WeaponLord, Davarae has said site staff is working on the issue (https://www.speedrun.com/The_Site/thread/k6o27). Keep in mind that it is around finals time for many schools and colleges, so it may be a while before they have the time to fix it.
