====== Upload additional file types in WordPress ======
This fixes the error "Sorry, This File Type Is Not Permitted for Security Reasons".

In ''wp-config.php'' add this:
  define('ALLOW_UNFILTERED_UPLOADS', true);

If you are not using some custome theme but a Wordpress builder of some kind, edit the ''wp-includes/functions.php''. Otherwise go to your theme folder functions.php file (''wp-content/themes/yourtheme/functions.php''. Add this to enable ''svg'' upload:

<code php>
// Allow additional MIME type upload
function my_custom_mime_types( $mimes ) {

// New allowed mime types.
$mimes['svg'] = 'image/svg+xml';
$mimes['svgz'] = 'image/svg+xml';

// Optional. Remove a mime type.
unset( $mimes['exe'] );

return $mimes;
}
add_filter( 'upload_mimes', 'my_custom_mime_types' );
</code>

These changes will most likely be overwritten on next theme or WP update.
