I cannot enter site in maintenance mode. Am fed up with this. Forum is useless. I search for "how do I enter site in maintenance mode?" and forum asks me if I meant "how do I after size in interface code?"
Too many unrelated results post. Unbelievable! Found one that was 7 years old. Did all the suggestions, nothing works.
I used the site.com/admin
Changed "update_free_access" in settings file.
