问题是事件调用者是在qtranslate、Tribe\\uu events\\uu Main：：instance（）之前初始化的：

       // let\'s initialize tec silly-early to avoid fatals with upgrades from 3.x to 4.x
        add_action( \'plugins_loaded\', array( $this, \'plugins_loaded\' ), 0 );

 add_action( \'plugins_loaded\', \'__fix_tribe_init\', 0 );

  function __fix_tribe_init(){
     global $locale;

     if(preg_match(\'/^\\/ru\\//\',$_SERVER[\'REQUEST_URI\'])) {
         $locale = \'ru_RU\';
     } 
}
