Field in custom module doesn't save

Hello community,

My Tech information

Sugar PRO 7.7.1.2 Onsite

PHP Version 5.6.24-0+deb8u1

  1. We create a simple custom package with a normal module inside
  2. We try to add or modifiy a field
  3. We save it
  4. Nothing field is not modify or create.

What we inspect :

  1. Directory 755 and 644 is ok
  2. File /custom/modulebuilder/packages/{package}/modules/{module}/vardefs.php was saved (timestamp change when we save), but no change inside...
  3. When we debug in sugar.log we see what we want to modify (populate with the value)
  4. When we add manually some field in vardefs.php, it's ok in module builder we saw the field.

We don't understand where is the bug. Have you some idea ?

Best regards

Fred
