Erro ao editar usuários

Bom dia …

Recentemente tive um problema ao utilizar uma área do OJS … e aparecer a seguinte mensagem: “Failed Ajax or Invalid JSON returned” . Consegui resolver com uma resposta aqui do fórum…

Contudo, o mesmo erro se da agora em outra área, na página de usuários, conforme mostra abaixo. O erro acontece ao clicar em Editar Usuários.

No terminal o erro que mostra é esse :
