Solved: “Publishing failed. The response is not a valid JSON response” error on WordPress

Have you recently installed WordPress and tried to create a new page only to be greeted by "Publishing failed. The response is not a valid JSON response"? Here's how to fix it!

  1. Either go to your web files via FTP or the file manager of your hosting’s Site Tools/cPanel
  2. Go to the root of your WordPress installation, somewhere like server/public_html/
  3. Now locate the .htaccess file (this may be hidden if you are looking at it from your browser, you need to toggle your visibility settings) and simply delete the file (I promise it’s okay!)
  4. Now go to WordPress site/wp-admin > Settings > Permalinks > *select your desired setting if required* > Save Changes – do this twice
  5. A new .htaccess will automatically be created – you can go back to your WordPress files and check

You should now be able to create pages with no issues!
