Well,
It works fine for me. Try installing the docs for muttrc again. I tried the command <locate muttrc>, the output was:
Code:
/usr/lib/mutt/source-muttrc.d
/usr/share/doc/mutt/examples/ray.muttrc
/usr/share/doc/mutt/examples/sample.muttrc.gz
/usr/share/doc/mutt/examples/sample.muttrc-tlr.gz
/usr/share/doc/spamassassin/examples/muttrc
/usr/share/man/man5/muttrc.5.gz
/usr/share/vim/vim70/ftplugin/muttrc.vim
/usr/share/vim/vim70/syntax/muttrc.vim
You can check too. If other man pages work, then the problem lies with the muttrc docs.
