Hi, I'm new to all this. I'm at the end of tutorial 2 and just rebuilt database and get told this:
Warning: Cannot modify header information - headers already sent by (output started at /home/bookcell/public_html/sapphire/core/model/DatabaseAdmin.php:137) in /home/bookcell/public_html/sapphire/core/Debug.php on line 151
The website server has not been able to respond to your request.
...so I can't get into the CMS. How can I fix the problem?
