Hello @alessandromelo88, sorry to hear you are facing issues with saving stories. Note that the Web Stories plugin needs to communicate with the REST API to save stories, load media, publish stories, etc. Could you check a couple things:
1) Do you see any warnings or errors about REST API when checking your Site Health status (Tools > Site Health > Status)?
2) If possible, could you check for any?browser console errors?in the browser dev tools and send us a screenshot?
3) If you have access to the PHP error/ WP DEBUG logs, you can check for any errors in the log that could help identify the issue.
Temporarily setting define( ‘WP_DEBUG’, true ); and define( ‘WP_DEBUG_DISPLAY’, true ); in your wp-config.php file should show you an additional error message that can help us track down the issue.
You can reach out to your hosting provider if you’re unable to edit that file directly or need their help to provide the server logs.
