TYPO3 6 Debugging of a 500 internal server error
In order to debug a TYPO3 6.1 Website, where only a white page is displayed (as result of a 500 internal server error), you can enable the displayErrors in a similar way then in earlier versions of TYPO 3.
Just edit the LocalConfiguration.php which is located within the typo3conf directory and add the following entry:
... 'SYS' => array( ... 'displayErrors' => '1', ), ); ?>
But, don’t forget to remove this entry after debugging 😉
