 * I can’t use the Customizer, I get these errors:
 * PHP Notice: Undefined variable: preset in C:\Users\richa\MyFiles\wwwroot\westwalesdas\
   wp-content\plugins\my-calendar\includes\widgets\class-my-calendar-today-widget.
   php on line 150 PHP Notice: Undefined variable: preset in C:\Users\richa\MyFiles\
   wwwroot\westwalesdas\wp-content\plugins\my-calendar\includes\widgets\class-my-
   calendar-today-widget.php on line 150 PHP Notice: Undefined variable: preset 
   in C:\Users\richa\MyFiles\wwwroot\westwalesdas\wp-content\plugins\my-calendar\
   includes\widgets\class-my-calendar-today-widget.php on line 150 PHP Notice: Undefined
   variable: preset in C:\Users\richa\MyFiles\wwwroot\westwalesdas\wp-content\plugins\
   my-calendar\includes\widgets\class-my-calendar-today-widget.php on line 150 PHP
   Notice: Undefined variable: preset in C:\Users\richa\MyFiles\wwwroot\westwalesdas\
   wp-content\plugins\my-calendar\includes\widgets\class-my-calendar-today-widget.
   php on line 150
 * My fix is to define the variable: $preset = “” but this has to go in the class-
   my-calendar-today-widget.php file, which is going to get overwritten with updates.

 * Are you up to date with the latest release? This specific issue was fixed in 
   3.6.12, so it shouldn’t be happening if you’re up to date.

 * Very nice plugin, thanks
