Hi. Since installing CB on Joomla, the CB template has not worked.

I have tried hard coding the template images' addresses, checking the setup locally, switching between various templates and so on. The problem persists irrespective of browser or template.
The server runs recent releases of PHP and MySQL.
The only issue I can find is that IE6+ does not recognize some of the CSS coding, but this should not affect Safari, Firefox, etc.
This problem is holding back site development and prospective users are getting impatient, damaging their trust in both myself and in CB as an acceptable site component.
I quite like CB and would prefer to stay with it after all the time and effort put in.
Any ideas how to resolve this issue?
Keep up the good work.
