  Mobile Theme Fatal Error

  The following fatal error is displayed when users try to access our site using a mobile device and when I try to preview the mobile theme on the themes tab under system preferences:
  
  Fatal error: Uncaught exception 'Exception' with message 'TeraWurflRemoteClient Error: Could not query Tera-WURFL master server.' in /hsphere/local/home/c372773/watccourses.com/ATutor/themes/mobile/include/TeraWurflRemoteClient.php:160 Stack trace: #0 /hsphere/local/home/c372773/watccourses.com/ATutor/themes/mobile/include/TeraWurflRemoteClient.php(99): TeraWurflRemoteClient->callTeraWurfl('http://wurfl.th...') #1 /hsphere/local/home/c372773/watccourses.com/ATutor/themes/mobile/include/header.tmpl.php(63): TeraWurflRemoteClient->getCapabilitiesFromAgent(NULL, Array, 'json') #2 /hsphere/local/home/c372773/watccourses.com/ATutor/include/classes/Savant2/Savant2.php(1325): include('/hsphere/local/...') #3 /hsphere/local/home/c372773/watccourses.com/ATutor/include/classes/Savant2/Savant2.php(1354): Savant2->fetch('include/header....') #4 /hsphere/local/home/c372773/watccourses.com/ATutor/include/header.inc.php(291): Savant2->display('include/header....') #5 /hsphere/local/home/c372773/watccourses.com/ATutor/mods/_core/themes/i in /hsphere/local/home/c372773/watccourses.com/ATutor/themes/mobile/include/TeraWurflRemoteClient.php on line 160
  
  Research indicates there is a patch to correct errors for the mobile theme. All of the patches ( #4848 and it's fixes, #4949 and #5337) in our patcher list have been installed. Where can I find the patch for the mobile theme.
  
  Will the patch correct this error?
  
  If not what is the next step?

  Re: Mobile Theme Fatal Error

  There was not a patch for 2.0.3, but the one for version 2.1 should work, though you'd need to manually apply what's described in the patch.

  Re: Mobile Theme Fatal Error

  We manually applied the patch. We are now getting a different error.
  
  This is the new error:
  Fatal error: Call to a member function getDeviceCapability() on a non-object in /hsphere/local/home/c372773/watccourses.com/ATutor/themes/mobile/include/header.tmpl.php on line 138

  Re: Mobile Theme Fatal Error

  It would appear you are using a custom version of the mobile header template. Line 138 above does not exist in distribution version of the file.
  
  https://github.com/atutor/ATutor/blob/atutor_2_1/themes/mobile/include/header.tmpl.php#L138
  
  You might take a fresh copy of the file from the link above, then comment out lines line 59 to 63
  
  https://github.com/atutor/ATutor/blob/atutor_2_1/themes/mobile/include/header.tmpl.php#L59-L63
  
  Otherwise if you want to keep the custom version, remove lines 138 to 140.
