When I updated today, I got stuck in maintenance mode. My update screen showed the "Down for Maintenance. Please check back in a few minutes." which normally appears on the site.
Now, my site has this warning on the front and back ends:
Warning: Invalid argument supplied for foreach() in /home/content/94/9852494/html/wp-content/plugins/jetpack/jetpack.php on line 4527
I would gladly reupdate, but I cannot find just the update.
