Fellglow Keep Blocked Up

[AuleCraft]

So I'm in the middle of the quest 'Hitting the Books' and can't progress through Fellglow Keep. The stairway leading up to the ritual chamber is blocked off, just like it would be if I hadn't started the quest. Very, very frustrating. Any help would be appreciated!! The mods I'm running are as follows:

Try using the console to disable the obstruction? Assuming you're on a PC, of course.

[MightyZ0G]

there is another stairway that isn't blocked by rubble. just keep exploring ;)

[CrimsonNytefall]

I've looked EVERYWHERE, and I can't find a way through. :T

What perhaps might that command be? Also, is there a command to reset the "cleared" status of Fellglow Keep? I think that might do the trick.
