WordPress: "Routine maintenance is being performed, please come back in a minute" solution

When WordPress is upgrading programs, themes, and plug-ins, if the network abnormality causes the upgrade to fail, it is easy to prompt: "Routine maintenance is being performed, please come back in a minute" error, and the front and backend of the website cannot be accessed normally. Share below How to fix this problem:

Log in to the root directory of the website, find and delete .maintenance, and then refresh (or clear the browser cache) to return to normal.

Under normal circumstances, the above method can solve the problem of "Routine maintenance is being performed, please come back in a minute." However, under special circumstances we may not be able to find .maintenance in the root directory of the website. document.

Then you need to open the wp-admin/includes/class-wp-filesystem-direct.php file and modify the following code.

function mkdir($path, $chmod = false, $chown = false, $chgrp = false) {
// safe mode fails with a trailing slash under certain PHP versions.
$path = untrailingslashit($path);
if ( empty($path) )
return false;

if ( ! $chmod )
$chmod = FS_CHMOD_DIR;

if ( ! @mkdir($path) )
return false;
$this->chmod($path, $chmod);
if($chown)
$this->chown($path, $chown);
if($chgrp)
$this->chgrp($path, $chgrp);
return true;
}

Change to the following code:

function mkdir($path, $chmod = false, $chown = false, $chgrp = false) {
// safe mode fails with a trailing slash under certain PHP versions.
if ( ! $chmod )
$chmod = $this->permission;
	
if ( ini_get('safe_mode') && substr($path, -1) == '/' )
$path = substr($path, 0, -1);
	 
if ( ! @mkdir($path) )
return false;
$this->chmod($path, $chmod);
if($chown)
$this->chown($path, $chown);
if($chgrp)
$this->chgrp($path, $chgrp);
return true;
}

After that, return to the root directory of the website, you can find the .maintenance file, and delete it according to the above method.
