I suppose others might have same problem. Just reflashed from power-kernel v48 to v49. Same outcome...

I know a workaround tho
-1- flash to stock kernel only
-2- initialize database cq get it sorted out
-3- context menu "Start File Browser Here"; set one of the subdirs of /home to be the default dir
-4- install power-kernel + nitdroid
-5- refresh database only by updating/autoupdating the database. You can manoeuvre freely from the first level under /home and below. If you arrive at /home you cannot go below anymore. What remains is that you enter via the chosen subdir (see3).
