I am trying to redirect http://test.pearlsquirrel.com/explore_all?u=hiphop to http://test.pearlsquirrel.com/explore_all/hiphop using htaccess. However, It keeps redirecting here: http://test.pearlsquirrel.com/explore_all/?u=site_error.php. I have looked all over Stackoverflow for the answer but I just can't seem to find it. I would really appreciate some help in fixing this problem, thanks!
Here is my .htaccess file
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.pearlsquirrel.com$ [NC]
RewriteRule ^(.*)$ http://pearlsquirrel.com/$1 [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^/]+)/$ $1.php
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+) explore_all?u=$1 [L]
