Keep your .htaccess like this:

Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /profile/

# new rules
RewriteCond %{THE_REQUEST} \s/+profile/?(?:index\.php)?\?([^\s&]+) [NC]
RewriteRule ^ %1? [R=302,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/.]+)/?$ index.php?$1 [L,QSA]

# php hiding
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+?)/?$ $1.php [L]
