 * This plugin caused my wp-content folder to disappear twice. I had to go back 
   in my history to restore my site. This is the error I got when I submit a post
   then lose my site:
 * Unknown modifier ‘H’ in /home/content/19/5307519/html/wp-content/plugins/wordpress-
   seo/admin/class-metabox.php on line 1690
 * I looked into the plugin and I did not see an H in line 1690 of the class-metabox
   of the plugin. I disabled the plugin, but I need the plugin. I will wait to see
   what the fix is, but I will have to move on if the error isn’t realized and corrected.

 * Hi,
 * I’ll send a pull request to Yoast with the solution for the error, hopefully 
   it’ll make it into a next version of the plugin. In the mean time, you can solve
   it by changing line 1690 in file /wp-content/plugins/wordpress-seo/admin/class-
   metabox.php to:
 * `if ( !preg_match('%\b'.$job['keyword'].'\b%', $firstp) && !preg_match('%\b'.
   $job['keyword_folded'].'\b%', $firstp) ) {`
 * By the way: there is no way that this error is causing your wp-content folder
   to disappear, so there must be something else wrong with your site as well.
 * Smile,
    Juliette
