Em qual versão você está? Estável, Beta ou testes-aprovados?

Parece que @gerhard corrigiu isso há 10 dias. Houve algumas migrações da versão 6.0 que causaram problemas com a **stable**.

> [@Stable release v2.3.6 upgrade bumpiness due to plugin](https://meta.discourse.org/t/stable-release-v2-3-6-upgrade-bumpiness-due-to-plugin/133008/4?u=stephen):
>
> I fixed the migrations in [FIX: Make migrations work with Discourse stable · discourse/discourse-policy@94635bf · GitHub](https://github.com/discourse/discourse-policy/commit/94635bf21761eefa4bbe0f33e18e9b9af6a9dcd4). I hope there was nothing else in the last couple of commits that breaks on the stable branch.

Execute:

`git pull`  
`./launcher rebuild app`

Ou, se você renomeou seu app.yml para myapp.yml: `./launcher rebuild myapp`

Tente novamente e nos avise se não funcionar.

Sim, já fiz isso algumas vezes.  
Não está funcionando.

Corrigi a migração no plugin Akismet. Por favor, teste reconstruindo seu aplicativo.
