Reseller sync stuck - php.ini custom

[Onir]

Hello! after the recent update of plesk

Product version: 12.0.18 Update # 18

     Update date: 10/01/2014 16:24
      Build date: 08.21.2014 14:00
    Build Target: CentOS 6
        Revision: 333059
    Architecture: 64-bit
Wrapper version: 1.1

Resellers can not create new domains.
the error returned is related to a custom configuration of php, the domains included in the plan with custom php configuration no longer able to sync and you can not create new ones under that plan.
