500 error accessing admincp
 

I was trying to change my attachment storage type from database to file system when this happened. I am not sure but I may have mistyped my folder path wrong. After I enter the path and clicked the for the next step the paged refreshed with a 500 internal server error. Now I have no access to my admincp nor can users view the forums.

Is there something I can do to get back to my admincp?
