Turn off the frontend ExceptionHandler

to get exceptions in your frontend

To display exceptions on your TYPO3 website in frontend, you need to turn off the cObject exception handler.

In TYPO3 backend navigate to WEB > Template > Setup and paste the following code into your templates setup:

 

config.contentObjectExceptionHandler = 0

 

This should only be used while you are developing on a website. Be sure to turn on the exception handler on production websites.
