Hi, Since I cannot reproduce this (as I said, none of my 4.4 devices (Nexus 7, Moto G) have issues with permissions), could you please replace web_server.py in Mnemosyne/web_server with the attached version?
It will print out extra output, like name and path of the database loaded, the webrequests coming in, and the html that will be served. You will need to move back to the python console after launching requests from your webbrowser in order to see this debug info, though. Good luck!
