the server continues run, can see, can't write log being generated. i've tried these fixes far: -used chmod 755 , 777 change permissions on full path -changed path current one(old 1 creating log in project folder) -used chmod 755 , 777 change permissions on new full path

here's setting.py code:

please let me know if need else me.

you need fix permissions chmod command
try command:

chmod 775 /users/prog/documents/guestbook.log
