My website is stuck in maintenance mode

 I have a message on my site:

"Briefly unavailable for scheduled maintenance. Check back in a minute."

Solution:

You need to go into the file structure of the site (not through WordPress, but through your Cpanel or an FTP program) and look for the file titled:

.maintenance

and delete it.

Then refresh your website page (you can do this by pressing F5 on the top of your keyboard).
