Just to get past the error I removed the =0 and =null's in the function template. Next error was PHP Parse error: syntax error, unexpected '&', expecting T_VARIABLE or '$' in /var/www/html/dolphin61/templates/base/scripts/BxBaseCmtsView.php on line 176

I removed the & (which I'm sure introduces some other bug!) and the homepage came up.

Not sure if these require PHP 5 -- but looks like if you can program a different way, you may be OK in PHP 4.4.6.

thanks,
Rowland
