Hello, thank you very much for your reply. As suggested, I’ve just tested with an official theme (twenty-twenty-four) and I have exactly the same issue. So the problem seems to be coming from somewhere else.And my WP version is up to date too.In other words, but in principle it shouldn’t be a source of problems, I’ve used the options (menu on the right in the editor) to resize the blocks and I’ve added a posts excerpt block which works without a problem. :-/
