WordPress stuck with “Briefly unavailable for scheduled maintenance…”
Today I went to update some plugins on one WordPress installation but then I accidentally closed the tab while update was in process. When I went back to WP admin or (to blog homepage) I was getting this error: “Briefly unavailable for scheduled maintenance. Check back in a minute“. Since I couldn’t access WP Admin my hands were tied and I could do anything. So I logged in at the FTP to see how the plugins folder looks like and is something damaged. And in www (pubic_html) folder I noticed file “.maintenance“. I made backup of it and then deleted it and reloaded the blog and – IT WAS WORKING AGAIN! And WP admin was working again! WordPress never stops amazing me!
