I want to use Gutenber in my site, but all post and pages always edit with the editor clasic. I've uninstalled clasic editor, and also all related plugins I had been using in the past. However, nothing happens. I can not use gutenberg. I installed Gutenberg Version 12.7.2 but I can not find where I need to configure or what I need to do more... It is really frustrating. Is there some configuration in the wordpress files where I can find another solution to force Gutenberg use technically? maybe some .php configuration file?
