I have found that removing the mythweb dir and copying over the new one 
works better then just copying over the top of the existing directory. 
(that way you KNOW you have a fresh copy)

mv /var/www/html/mythweb ~/mythweb.old
ll /var/www/html (you should *NOT* see the mythweb DIR)
cp /<mythweb-source-DIR>/mythweb /var/www/html/
/sbin/service httpd restart
(if it work then remove the old copy)
rm -rf ~/mythweb.old
