EDIT: I noticed that MyDocs and anything under it is shown as drwxr-xr-x file permissions. MyDocs and all files are owned by root and by group root. Is that what it supposed to be? (I never paid attention to these details before when it was still working...) I was able to change the MyDocs directory owner and group to user users but it automagically changed back to root root after little while.
