Breaking: #88376 - Removed obsolete "pageNotFound_handling" settings¶
The following global TYPO3 settings, usually set within
LocalConfiguration.php have been removed:
These settings are effectively replaced by the error handling of the newly introduced Site Handling which is more flexible and robust, and is used instead of these options when Site Handling was enabled in TYPO3 v9. For TYPO3 v10 Site Handling is a requirement, making these options useless.
Setting any of the options will have no effect any more. Executing the Silent Upgrade Wizard will remove the settings automatically.
Any TYPO3 installations having these settings overridden in
file of an installation.
Access the install tool to automatically update the
LocalConfiguration.php file and remove the
Ensure to set up Site Handling with proper error handlers. Avoid accessing these settings but
rather use the available
TYPO3\CMS\Frontend\Controller\ErrorController class, when trying to manually trigger a 404/500
in the Frontend (e.g. custom plugin) instead.
