500 - behavior::tabstate not found.

Post by rikaryo » Tue Dec 07, 2021 9:03 pm

Friends, when migrating everything right from the J3.10.3 site to J4.0.4, everything worked just fine, but when you go to edit content already posted by the front, the error appears: 500 - behavior::tabstate not found.

I modified the layout of the post and editing and it still doesn't work.

Has anyone been through this that can show me a possible solution?



Amigos ao migrar tudo certinho o site J3.10.3 para J4.0.4, tudo funcionou certinho, mas quando vai editar um conteudo já postado pelo front surge o erro: 500 - behavior::tabstate not found.

Modifiquei o layout da postagem e edição e mesmo assim não resolve.

Alguém já passou por isso que possa me mostrar uma possivel solução?
