I’ll introduce how to fix the issue when WordPress displays the message “Currently under maintenance, temporarily unavailable.”

How to fix "Currently under maintenance, temporarily unavailable."

Immediately after updating WordPress version, the message “Currently under maintenance, temporarily unavailable.” is sometimes displayed.

SSH login to the server hosting the WordPress site, and there should be a .maintenance file created in the project root, so delete it.

$ ls -al
total 532
drwxr-xr-x  5 nginx nginx   4096 Jun  9 22:01 .
drwxr-xr-x  4 root  root    4096 Jun  9 02:00 ..
-rw-r--r--  1 nginx nginx    344 Oct  6  2012 .htaccess
-rw-r--r--  1 nginx nginx     33 Jun  9 22:01 .maintenance

$ rm .maintenance

When “Currently under maintenance, temporarily unavailable.” appears after WordPress updates, it can be alarming, but since you just need to delete .maintenance, stay calm and handle it.

That’s all from the Gemba.
