I tried to count the lines in your code and got to around where your sql call is to check the user and password.  I have never seen anyone combine the query with the execution command before.  Just for kicks, (if my count is accurate), I would seperate the following command:






$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' AND activated='1' LIMIT 1");








To:






$sql = "SELECT * FROM users WHERE username='$username' AND password='$password' AND activated='1' LIMIT 1";
$r=mysql_query($sql);
if (!$r) {
echo "Unable to query data."
session_destroy();
exit;
}








 



I hope I have helped some.

With that u mean u never saw someone writing the string query inside mysql_query()? But just saw it written as $sql="SELECT..."; mysql_query($sql)??? If my assumption is right then u probably havent seen too much, as its a very common coding method.


 



U could use:


 






$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' AND activated='1' LIMIT 1") or die(mysql_error());







 



so u know whats happening. To me the query looks alright but u may have problems in the connection.

Although your query shouldn't have any problems, I do have to question the use of " * ". You can easily go around this. Selecting the whole table in mysql is a huge no no. You can just tell mysql to select username from users instead of using the where clause. - I would recommend it.
