Vanity URL Error: Object Not found

[seko3]

For some reason I am getting a vanity URL error, and no other posts have sufficiently answered the question. What's wrong with the PHP code?\[code\]if (isset($_GET['username']) === true && empty($_GET['username']) === false) {$username = $_GET['username'];echo $username;}\[/code\]and my \[code\].htaccess\[/code\] file is: \[code\]Options +FollowSymLinksRewriteEngine OnRewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ /lr/profile.php?username=$1\[/code\]If I go to \[code\]/projects/lr/profile.php?username=harrison7042\[/code\], it works but if I go to \[code\]/projects/lr/harrison7042\[/code\] it doesn't work and just returns: \[code\]Object not found!\[/code\].If I change this line:\[code\]RewriteRule ^(.*)$ /lr/profile.php?username=$1\[/code\]To this:\[code\]RewriteRule ^(.*)$ projects/lr/profile.php?username=$1\[/code\]The server returns an \[code\]Internal Server Error\[/code\]. I'm not sure what I am doing wrong, or what. I followed along perfectly with the tutorial here.Thanks, Harrison
