I have a problem with the maintenance mode and the home page. Once I have activated the maintenance mode I can no longer access my home page by being logged in either by using the dashboard or by changing directly from the url.
Without admin access, I can’t tell exactly what’s the problem, unfortunately. All I can advise is to deactivate all plugins that are not related to our theme and try to use the “Maintenance” mode from our theme in Theme Settings -> Maintenance.
