.. include:: /Includes.rst.txt ========================== TYPO3 Exception 1481496170 ========================== .. include:: /If-you-encounter-this-exception.rst.txt .. TYPO3 12.4.x - 14-4-2025 ================================== Exception text -------------- 503 Flex form displayCond on field "" on flex form sheet "" references a field or field / sheet combination "" that might be defined in given data structure but is not found in data values. The Issue --------- If the exception occurs in the backend when a non-admin editor tries to insert a new content element or plugin, then probably this is a matter of permissions: a field that the user has access to references another field to which the user has no access. Most likely in a 'displayCond'. Solution -------- Check the access rights for this user, in the usergroups the user belongs to. Find the section 'Allowed excludefields [non_exclude_fields]' and look for the flexform belonging to this content element or plugin. Then make sure to either check, or uncheck all fields that reference each other.
