ok but i keep getting preg_match errors. Any help? Thanks :happy:

Replace all the calls to preg_match() with ereg(). Ereg takes the same parameters as you are using for preg_match at the moment.

See if that fixes it.

I'm not the best person for debugging regex, but this may solve a part of the problem:

if(!preg_match("**/[-0-**9A-Z_@\$\+\.\\/", $avatar)){

Try removing the - before the 0.

 //password
if($pass != $pass_2){
print "<br>Both Passwords Must Be The Same";
}else{
$password_edit = "UPDATE `users` SET `password` = '$new_pwd' WHERE `name` = '$username_cu' LIMIT 1";
$password_update = mysql_query($password_edit) or

mysql_error();
}

Added the single quotes around $username_cu, and where is $new_pwd being defined?

Why so many UPDATE queries?
