Joomla! Discussion Forums

Whenever I change the name of a template that I have assigned as the default template and then re-upload it to the server it doesn't pick up the name change of the template. Is there a place in the database where I can change the association to the template?

OH and while I'm this database subject where can I find a RDB Schema of Joomla 1.5's tables and how they relate to each other?

Thanks,
Tony
