Re: Fatal error: Call to undefined function wp()
My guess is you have a config error in your bb-config.php. Loading this page:
Gets me this error:
Parse error: syntax error, unexpected T_STRING in /home/philipsh/public_html/bbpress/bb-config.php on line 22
Line 22 is around the database password. Maybe the previous line is not quoted properly or is missing the semi-colon. My guess is that you have an error in that file and if you fix that, things will probably be OK.
If you have a text editor with syntax highlighting, it will be easy to find the PHP syntax error that is causing this.
