TYPO3 Core

Hi Christian,

can you please post your PHP settings. Did you activate STRICT mode?
Usually the implicit conversion from integer to string should not issue a PHP warning.

My PHP settings for error_reporting is "E_ALL & ~E_DEPRECATED"

That should be ok.

Can you please post the complete error message from the log and maybe a stack trace?

This is the error message from sys_log:

Core: Error handler (FE): PHP Warning: explode() expects parameter 2 to be string, null given in /typo3_src-4.5.22/t3lib/class.t3lib_div.php on line 1950

Thanks for updating tslib_fe::initFEuser. But you forgot t3lib_userAuth::getAuthInfoArray :-)
It should be

@Christian: Indeed, I forgot about it.

Could you please file another forge issue and add this as related.
Feel free to add me as watcher as well.
Thanks.
