I have exactly the same error after upgrading today.

Al projects has been affected.

Can not change control type in any form. Got the same error

The previous error - re Data Type Select has been fixed.

Now I have issues with validation (AJAX).
It’s working fine except for the fact that I get an error message:
Undefined offset: 4 | Script: C:\Program Files (x86)\NetMake\v81\wwwroot\scriptcase\devel\class\generator
mDados.class.php linha: 6163

The system encouraged me to send this through, but to whom???

Is there a location, email, contact to lodge errors within the system.
I have only bought the product not the support.
regards
