nothing appears

I edited my htaccess file as such:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
AddType audio/ogg ogg
AddType audio/ogg oga
AddType video/ogg ogv
AddType video/mp4 m4v
</IfModule>
# END WordPress

and also put the “AddType” lines after the </IfModule> tag. Doesn’t work both ways. I’m using the
[hmp_player]
shortcode. The site is in maintenance mode at the moment. Log in as a subscriber as WPHelp with the pw helpmen0w
