Nice tutorial. The only proplem I have left is all the:

"Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in"

erros I get. I guess this is also a setting in php.ini but I did not manage to find any solution Googling around.

I also wonder why it's necessary to use the php.ini.default-5.2-previous file and why the php.ini.default for 5.3.0 works?
