Please contact Variablez and ask him to make you an account if you need to!");}

one ip per acount mod on this page:

<?phpinclude "config.php";global $_CONFIG;define("MONO_ON", 1);require "class/class_db_{$_CONFIG['driver']}.php";$db=new database;$db->configure($_CONFIG['hostname'], $_CONFIG['username'], $_CONFIG['password'], $_CONFIG['database'], $_CONFIG['persistent']);$db->connect();$c=$db->connection_id;$set=array();$settq=$db->query("SELECT * FROM settings");while($r=$db->fetch_row($settq)){$set[$r['conf_name']]=$r['conf_value'];}//thx to [url=http://http://www.phpit.net/rg-erdr.php?_rpo=t; for valid_emailfunction valid_email($email) {  // First, we check that there's one @ symbol, and that the lengths are right  if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) {	// Email invalid because wrong number of characters in one section, or wrong number of @ symbols.	return false;  }  // Split it into sections to make life easier  $email_array = explode("@", $email);  $local_array = explode(".", $email_array[0]);  for ($i = 0; $i < sizeof($local_array); $i++) {	 if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) {	  return false;	}  }    if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name	$domain_array = explode(".", $email_array[1]);	if (sizeof($domain_array) < 2) {		return false; // Not enough parts to domain	}	for ($i = 0; $i < sizeof($domain_array); $i++) {	  if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i])) {		return false;	  }	}  }  return true;

and theres more but i think its somwhere in there? any idea? any help please?

Notice from rvalkass:

Code needs to be in code tags. Also moved to the PHP section of the forums.

Looking at the 'SQL Data' configurations, looks like this code will probably have to go in your config.php file, or the variables will have to go in your register.php file. If that doesn't work, it probably goes into your login.php because of the "Someone is already using this computer's address...". It could be either. Plus, how did you find this code/error in the first place?

I think it would be best to contact mccodes for this. They will most likely give you better help, unless there are advanced mccodes users here...

$username=$_POST['username'];$username=str_replace(array("<", ">"), array("<", ">"), $username);$q=mysql_query("SELECT * FROM users WHERE username='{$username}'",$c);If(mysql_num_rows($q))

It is saying that the last line posted is wrong. I am 100% new at this and I am working little by little. I am not sure why it is wrong. The posted error msg is below:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/jokers/public_html/register.Php on line 6

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/jokers/public_html/register.Php on line 75

Then when I login it says:

No database selected
