Mesmo problema aqui. Tudo cadastrado e ativado, mas ao tentar fazer o pagamento em ambiente de teste, dá este erro. Erro ao finalizar a compra. Tente novamente. Woocommerce + Mercado Pago.
Acho que o ideal mesmo é usar outro Gateway.
Refresh the page and see if it loads.
As a friend, the site is down because of this plugin, and the hostinger technicians were unable to resolve it, they just confirmed that the problem is with this plugin.
I will have to format my installation, and upload everything again, only now without this plugin, obviously.
