I am having a very similar problem. I finally completed my install and when I try to login with the default username and password I can't log in. I get this error:
Not Found
The requested URL /public_html/mt/mt.cgi was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.33 Server at www.mightythings.net Port 80
This is my CGI Path script:
CGIPath http://www.mightythings.net/public_html/mt/
I followed the TCH installation instructions (without secureCGI) so MT is installed in /public_html/mt/
My other mt.cfg edits look like this:
# DataSource ./db
ObjectDriver DBI::mysql
Database xxxxxxx_mtdatabase
DBUser xxxxxxx_mtadmin
# DBHost localhost
Thanks in advance.
