I've started the Pilgrims path quest, and spoken to the Nightingale Sentinel.
Took the journal from the skeleton and all. But the quest is not active! No marker and if i use Clairvoyance it just say's "No quest active" It's in my quest-log and it stands as active. I have tried Turning it off then on, I have tried nearly everything please help.

PLEASE HELP

Quickly said, quest stands as active yet it does not work.

That's not a Bug. You have to find the way yourself.

Indeed and this is not the only quest where you don't see the marker.
