 * I know this plugin hasn’t been updated in a bit, but it looks really cool.
    trouble
   is, I get some nasty warnings & notices when I try to activate it:
 * `Warning: Invalid argument supplied for foreach() in [path_to_install]/wp-content/
   plugins/detector/lib/Detector/Detector.php on line 77`
 * `Notice: Undefined property: stdClass::$csstranforms in [path_to_install]/wp-
   content/plugins/detector/lib/Detector/lib/feature-family/featureFamily.php on
   line 158`
 * Debug Bar also outputs the following:
 * `WARNING: wp-includes/functions.php:932 - Cannot modify header information - 
   headers already sent by (output started at [path_to_install]/wp-content/plugins/
   detector/lib/Detector/Detector.php:77)`
 * `WARNING: wp-includes/functions.php:945 - Cannot modify header information - 
   headers already sent by (output started at [path_to_install]/wp-content/plugins/
   detector/lib/Detector/Detector.php:77)`
 * `WARNING: wp-includes/functions.php:3725 - Cannot modify header information -
   headers already sent by (output started at [path_to_install]/wp-content/plugins/
   detector/lib/Detector/Detector.php:77)`
 * `WARNING: wp-admin/admin-header.php:9 - Cannot modify header information - headers
   already sent by (output started at [path_to_install]/wp-content/plugins/detector/
   lib/Detector/Detector.php:77)`
 * Anyone have ideas on how to fix?
