Weathermap editor permission issue

hi there,
i have the same exact problem than:

from the editor, my maps are read only.

Did you ever solve this?

I have exact same problem. Cannot edit files (read-only) Permissions are as recommended by documentation

What i did was to change ownership of the file .conf as
-rw-r–r-- 1 www-data librenms

Now i can both edit and view
