 * Hello
    I’ve added a filter in functions.php. It works when viewing the website
   on a computer but not on a mobile device (unless you choose ‘View Full Site’).
   How can I get the filter to work all the time? Thanks! Jackie

 * Yes is that the problem? I run a multisite and don’t want to use the filter on
   all blogs.
