Debug exception handler

Functions of \TYPO3\CMS\Core\Error\DebugExceptionHandler:

  • Shows detailed exception messages and full trace of an exception.
  • Logs exception messages via the TYPO3 logging framework.
  • Logs exception messages to the sys_log table. Logged errors are displayed in the belog extension (ADMIN TOOLS > Log). This will work only if there is an existing DB connection.
