+----
+
+I'm using boa and getting some odd behaviour if I don't set the `umask`
+option in the config file. Editing a page through the web interface and
+hitting "Save Page" regenerates the `index.html` file with no world-read
+permissions. As a result, the server serves a "403 - Forbidden" error page
+instead of the page I was expecting to return to.
+
+There are only two ways I found to work around this: adding a `umask 022`
+option to the config file, or re-compiling the wiki from the command line
+using `ikiwiki --setup`. Setting up a git back-end and re-running `ikiwiki
+--setup` from inside a hook had no effect; it needed to be at the terminal.
