Since MT is a paid software, why not contact their support team
directly?
I previously had problems with installation and had used full paths
in config.cgi and added "BEGIN { $ENV{'MT_HOME'} =
/home/blueskyw/public_html/mt/'; }" under use strict line in all
cgi files.
Although I have not used MT personally, I would suggest changing
the above setting to 'home/blueskyw/public_html/' and see if it
works for you.
Edit:
Ok never mind, seems like your search page and the others in the
mt/ directory are working. Let me poke around your site and I will
take a few more guesses later.
Edit2:
Argh. When did MT became open-source?
