Hello, I can´t install vbulletin in a RAQ 4, when I install display the below error message:

Checking your server against vBulletin's requirements ...

PHP version: 4.0.6 ... Passed!
MySQL support in PHP ... Failed! PCRE support in PHP ... Passed!
magic_quotes_sybase disabled ... Passed!
track_vars enabled ... Passed!
register_globals enabled ... Passed!

Need I change any configuration of PHP?

Thanks!!

check your php.ini file (use "locate php.ini" to find it) and look under the [mysql] section...

Add the following line if it isn't there:

extension=mysql.so

Thanks you, I changed the php.ini and now is working :D
