File permissions aren't inherited from parent directory on change. This is what ls's first column means: (rwx is read, write, execution)
[directory] [owner perms] [group perms] [everybody else's prems] d rwx r-x r-x As you can see, only owner (root, third column of ls) can write to the file. You can use chmod to allow everybody edit these files:
chmod go+w * or:
chmod a+w * First command means:
Allow (+) group members (g) and others (o) write (w) to the file, for all files (*).
Second one is
Allow everybody (a) write to the file.
