PHP Fatal error: Uncaught Error: Call to a member function

Olá,

Após a instala??o e ativa??o do Plugin, o site deixou de funcionar e apresentou o erro abaixo na log. Foi preciso remover o plugin para restabelecer o site, mas gostaria de resolver o problema para poder utilizar o plugin. Alguma ideia ou sugest?o?

Grato,
Diego
