Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at admin@localhost to inform them of the time this error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log. this is a part of the profile.php

profile.php

  // updatede for using the GET methode for ge the data nedded from the url 
    if(isset($_GET['u']))
    {
          $username = mysql_real_escape_string($_GET['u']);
          if(ctype_alnum($username))
         {


          //check user exist
             $check = mysql_query("SELECT user_name, first_name FROM user WHERE user_name = '$username' ")or die(mysql_error());
             if (mysql_num_rows($check)==1) 
             {
               $get = mysql_fetch_assoc($check);
               $username = $get['user_name']; 
               $fname = $get['first_name'];
             }
             else
             {
                echo "<h2>User does not Exist!!</h2>";
                exit();  
             }
          }
       }

        echo "$username";
?>

.htaccess

RewriteEngine On

RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1



RewriteRule^([a-zA-Z0-9_-]+)/$ profile.php?u=$1

Did you try adding whitespaces between RewriteRule and your rewrite rules? — Repox

I'm using my mobile browser so it's hard to tell, but I think your formatting is wrong there should be a space after rewriterule before the ^ — StrikeForceZero

yes their is a space between these 2 lines RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1 RewriteRule^([a-zA-Z0-9_-]+)/$ profile.php?u=$1 — user2172837

@user2172837 That's not what you are being asked; there's a big difference between this: RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1 and this: RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?u=$1 (the last example having a whitespace after RewriteRule). — Repox

I did - two times! You need to have a space between RewriteRule and ^([a-zA-Z0-9_-]+)$ profile.php?u=$1 in your .htaccess file. A space - the long button in the bottom of your keyboard. — Repox

why would you do such a thing, i've always used utf-8 without any problem

Amir Over a year ago

@Sebas I had experience about it. perhaps some apache servers have problem with it.

@user2172837, just save it in ANSI mode.hope this solve your problem. you can use windows Notepad and then save as, then select ANSI

Assuming that profile.php has no errors. Try to delete your last line of the .htaccess file. Also add a space between Rewriterule and '^'. Adding whitespace to the regex has nothing do to with this, because of the ctype_alnum() function. This only permits alphabetic characters.

Just copy and pase this to your .htaccess file and (ofcourse) delete the previous lines:

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?u=$1
