Hi @cesarvelame,
I’ll see if I can get one of our team members to weigh in further on your situation, but just a heads up that 3.3.0.5 was released recently - OJS/OMP/OPS 3.3.0-5 Released, which contains a critical security fix, so you may want to consider upgrading to that version (although, I realize that might complicate your situation further).
