N?o consigo usar o plugin

Boa noite,

Infelizmente o plugin n?o está funcionando em minha loja virtual, após configurado e ativado, fa?o um pedido teste e ao avan?ar para pagamento recebo um erro. No caso, n?o consigo nem avan?ar para a tela de “Thank you page”.

Este erro acontece tanto para o PIX quanto o Cart?o de crédito.

Segue abaixo o log:
