Thanks for fast reply, what is your email?
In case another new user of maintenance mode plugin has trouble here —
o When I accessed the site directly (though I was logged in as administrator) I did see the splash page
o I clicked the link in the bottom right of the splash page and logged in (again)
o I clicked the “visit site” link in the upper left of the dashboard
That gave me access to the front end.
found that and it helped
