The version 7.1.4 does not allow the definition of fields personalized in the Study. The version 7.1.5 allows neither the definition of fields personalized in the study, nor the field definition in the contructor of modules
Not really understanding the issue here. Can you not edit fields in studio/module builder?
If that’s the issue, could be permissions related.
I found de solution.
Configure php.ini with the next value:
error_reporting=E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_WARNING
