 * Hi!
    I have switched from classic to block editor. Creating a new block was ok,
   but when saving the changes, it said “Updating failed. The response is not a 
   valid JSON response.”
 * I have noticed that the page editor layout looks like block, but the functionality
   is still classic.
 * Now how can I either go back to classic or complete the conversion to block editing?
 * Thanks for your help!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fincomplete-switch-vom-basic-to-block-editor%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * The error “Updating failed. The response is not a valid JSON response” could 
   appear for several reasons.
 * First, you might want to go to Tools > Site Health.
 * If you can see an error related to “REST API”, clicking that will give you a 
   clue about the specific cause of the error.
 * If there’s no error in the Site Health, this may be a plugin or theme conflict.
 * Please attempt to disable all plugins and use one of the default (Twenty*) themes.
   If the problem goes away, enable them one by one to identify the source of your
   troubles.
 * If you want to go back to the classic editor, you can install this plugin: [https://wordpress.org/plugins/classic-editor/](https://wordpress.org/plugins/classic-editor/)

 * Hi and thanks!
 * The disabeling of all plugins did not help however, but the installation of classic-
   editor finally solved the problem.
 * Everything works again – many thanks!
