Troubleshooting Note
You might encounter a message at the bottom of the editor, saying “If this file was writable
you could edit it.” This indicates that the permissions for your WordPress files are set wrong
on your host server.
We talked about permissions in the “Get Permissions First!” sidebar in Chapter 11, “Installing
and Upgrading WordPress Software.” Briefly, the base file security on UNIX- and Linux-based
servers allows—and denies—access to files based on different types of users (Owner, Group,
and World).
If you're having trouble with permissions, go to the File Manager application in your host's
administration site (what this is called and how it looks depends on your host). You should find
the
WordPress
folder, then the
wp-content
folder. Both the folder and the files inside should be
listed as rwxrwxrw- (or 776). Under the
wp-content
folder, go to
themes
. These files should
have the same permissions listing. You should be able to edit the permissions directly; if you
can't, contact your host (after checking the host's help files) for assistance.
The Owner of these files should be the WordPress user (which may have a different name,
depending on what user owns the WordPress database). The Group includes the owner and
anyone else you've granted permission to post articles or comments on your blog. Theme files
should be group-writable.

Replacing Your Header Image
In Chapter 10, we explained the process of adding images to your blog posts. Changing your
header image consists of using your FTP client to upload your image to the server, and changing
one line in your CSS to point to that image. More precisely, follow these steps:
