Open takesignup.php
Find this:
PHP Code:
// check if email addy is already in use
$a = (@mysql_fetch_row(@sql_query("SELECT COUNT(*) FROM users WHERE email='$email'"))) or die(mysql_error());
And replace with this:
PHP Code:
// check if email addy is already in use
$a = (@mysql_fetch_row(@sql_query("SELECT COUNT(*) FROM users WHERE email=".sqlesc($email)))) or die(mysql_error());
That's all..
