Create a user whose preferred text editor is "Atto HTML editor". Create a forum that the newly created user will have permission to post/reply in. With the newly created user, go to reply to a post or create a new post. Enter some text into the "Message" text field. Wait at least 60 seconds and close the tab or log out. Verify that the message was autosaved into the mdl_editor_atto_autosave table select * from mdl_editor_atto_autosave Change the mdl_editor_atto_autosave table to a different name. ALTER TABLE mdl_editor_atto_autosave RENAME TO mdl_dave Go back to the form that you typed the message in (i.e. the form where the draft was saved). Observe that there is no database error being dumped into that text area. Also observe that a notification informing the user that there was an error retrieving their draft is displayed. Check the javascript console to see the debug output (in this case, a 'table not found' error should be displayed).
