Olá,
Atualizamos nosso fórum hoje para a versão mais recente, mas recebemos um erro HTTP 500 na página raiz. A seguinte mensagem aparece no arquivo production.log dentro do container quando a página raiz é aberta com erro 500:
Started GET “/” for 141.8.142.82 at 2021-08-25 21:44:06 +0000

Tentei recriar o container, mas o problema não desapareceu. A página de administração funciona sem nenhum problema. O que devemos fazer para reparar o fórum?
