Lovely error

umm.. Are you using php 5+ on apache 2.0+ ? By default, mysql service is disabled in php5. You need to add 2 lines in httpd.conf file in apache/conf.

LoadModule php5_module php5apache2.dll
AddType application/x-httpd-php .php

Open php.ini and uncomment mysql extension. Check the extension_dir folder in php.ini. Specify the right path of ext directory in php. ( eg. c:/php/ext). Copy libmysql.dll from php folder to system32 folder. Thats it. Restart apache.

Cheers,
Naveen

Done all of that when i set the server up a while ago nav33n thanks for the idea tho

UPDATE: i re-wrote the code for the database engine, i am now getting this error

Fatal error: Cannot re-assign $this in C:\Inetpub\wwwroot\forums\system\engines\database.engine.php on line 261

I see an error in this part of the code.

function getExecTime()
    {
      return round(($this->getMicroTime() - $this->timer) * 1000) / 1000);
    }

Another ) is missing in the return. Check if that solves your problem.

I noticed that but it doesnt help, i am totally stumped on the error message that php has given, as far as i know $this hasnt been reassigned
