This is my .htaccess file:
Options -Indexes
Options FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) /index.php?url=$1 [QSA,NC,L]
Now for testing purpose I create another directory name testproject on live site. What should do I change in this current .htaccess file?
Just change your RewriteBase to
RewriteBase /testproject
