 * Hi,
 * After many months of happy usage of Image Zoom, I get this error message:
 * _Fatal error: Call to undefined function wp\_is\_mobile() in /home/MYDOMAIN/public\
   _html/wp-content/plugins/image-zoom/image-zoom.php on line 181_
 * Deactivating Image Zoom solves the issue, but when reactivated (even after deleting
   and reinstalling the extension) the problem appears again.
 * Any thought?
 * BTW, I am not familiar with codes.

 * Let me guess … What is your version of WordPress ? Probably an old one (ie prior
   to 3.4)

 * I have 3.3.1, which is the newest (French) version. What do you recommend?

   seems to work.
 * Thanks.
