      Turn php off for the upload directory by placing a .htaccess inside it containing the following code:
      php_flag engine off

        Thanks alot bro you always seems to come to our rescue :D

          By any chance bro do you have any code that after 3 or 4 login attempts a person account is locked for 20 min or so?

            In short: Its too much hassle for me to do this properly for an lava script.
            If you don't do it properly you end up causing yourself more problems than its worth, as you need a multi ip protection system on it, as there is scripts that can hammer there way in via alternating ip addresses. (If you don't do it with ip protection you end up with users locking other users out of there accounts)

            Although You could "bodge" this together with cookies, but its not exactly hard to turn cookies off.

            My personal choice for a lava script would be to get rid of email addresses being shown to public in profiles and then changing the login credentials to email and password rather than name and password - This way a hacker would need 2 strings of data rather than just 1.

            You could then also email the user every time an incorrect password is entered or maybe even email yourself at the same time.

              Yes thats a great idea bro...you know you're very innovative. On my site password recovery you need to enter the username of the person and the email to send the recovery email so if the email is restricted from the public then a hacker probably will be in more pressure lol thanks alot
