I just saw that this plugin needed updating so I clicked to update it. Then I tried to click to go to a page on my site and got the error, "Briefly unavailable for scheduled maintenance. Check back in a minute." I've never seen that error before. It's been a while and my site is still unavailable. (I'm kind of freaking out because this is the site's peak time of week.) Please let me know how to rectify this. Thanks!
Never mind...figured it out. Deleted the .maintenance file in root directory and all is well. Thanks!
