Erro expired URL

Olá Cláudio!

Começou a ocorrer um erro com o plugin iugu ontem a tarde, em todas as as tentativas de pagamento com cartão ou boleto. O paypal e pagseguro continuam funcionando normalmente.

Copio abaixo o log:

Consegue me ajudar? Parece que o plugin está atualizado para a última versão.

Obrigado!!
