Breaking: #74533 - Throw exception if user function does not exist¶
GeneralUtility::callUserFunction() does now always throw an exception if the passed
user function does not exist or is not callable. The parameter
$errorMode has been removed,
exceptions are now always thrown. The method should not be called with more than three arguments.
Calling a not existing or uncallable user function leads to an exception, breaking the page output.
All TYPO3 installations are affected.
Remove or fix invalid
userFunc calls registered in TypoScript and/or
ext_localconf.php. Catch exceptions properly
