Problema para Instalar OJS 3.1

Estoy tratando de instalar la ultima version de OJS 3.1.1-1 en un hosting (Linux, PHP 5.6.25, MySQL 5.5.58) para probarla pero no puedo.

Cuando completo los campos solicitados en la instalación y le doy click al boton “Instal Open Journal System” arranca y vuelve enseguida de nuevo a la pagina de instalación sin tirar un error explicito…

Probe tambien de actualizar la version de PHP a 7.0 y lo mismo

Alguien me puede orientar cual podria ser el problema???

Estos son los mensajes que tira en el error-log
