 * Hi, first of all, thanks for the plugin. I use it a lot!
 * I wanted to inform you that there is a syntax error in /application/control/object/
   metabox.php.
 * The file is minified to one line which is nice, but some “// comment here” comments
   are used, which mark the whole line as a comment.
    The “/* comment here */” style
   should be used instead.
 * This causes a critical error which makes the WordPress site go blank until removing
   the comments in the file. Don’t know exactly on which servers it is critical,
   but I already had this on two different servers.
 * You might want to fix this in the next update. Cheers.
