Front Page still shows – all others show maintenance

Hi,

I love your plugin – use it for all our sites. Having an issue though with one, where the maintenance mode is working when you click on any site BUT the home page.

Cleared cache (and turned off cache plugin), checked with host and no cache files or plugin there, tried logged out, different browsers, incognito, etc.

I’m at a loss as to why it’s still showing the front page…

The page I need help with: [log in to see the link]
