#8 Help cleaning up tex errors

[Anonymous]

I've inherited care of a large sgml document using
docbook and sgmltools-lite. When I compile the
documents to ps I get pages and pages and pages of
warnings from Fancyhdr:

Package Fancyhdr Warning: fancyhdr's E option without
twoside option is useless on input line 26044.

These appear harmless but I'd prefer to get rid of them
if possible. Could you point out a few resources that
would tell me where I might be using Fancyhdr and how I
can fix these errors?

Thanks

Jacinta
