[TYPO3-mvc] Fe Users don't have access for their personal data on TYPO3 6.2

[Dmitry Vasiliev]

In class AccessControlService

     public function hasLoggedInFrontendUser() {
         //works
         return $GLOBALS['TSFE']->loginUser == 1 ? TRUE : FALSE;

         //does not work
         return $GLOBALS['TSFE']->loginUser === 1 ? TRUE : FALSE;
     }

Kind regards,
Dmitry Vasiliev
