 * I’m having trouble getting a number of the shortcodes to work. I’m specifically
   interested in [subscript] and [superscript].
    I have added the two shortcodes
   to the whitelist-plugin. But still no luck. Other shortcodes like [quote] and[
   spoiler] works fine. I’m wondering if has to do with either of the following 
   two problems:
 * 1)
    [code]Warning: Invalid argument supplied for foreach() in /home/ashome08/
   public_html/<domain>/wp-content/plugins/bbcode-deluxe/bbcode-admin.php on line
   15[/code] 2) [code]REMOTE_HOST - Your web server must be configured to create
   this variable. For instance, Apache needs HostnameLookups On in httpd.conf.[/
   code]
 * I’m not sure why this latter is necessary? At any rate: It’s impossible for us
   on our siteground account, as the HostnameLookups is a share setting for all 
   of the sites. This problem must apply to most shared-hosted users.
