Well, I have deleted all the posts I created before the update, and I am rewriting them. I don't think it has solved the problem, but at least for now, it is working that way. It seems that the Penci podcast plugin is causing conflicts, as well as the classic WP editor. I have already removed them. So, don't access the page anymore, I will continue working like this, and if I encounter any other issues, I will let you know.
