Error Message:
Briefly Unavailable for Scheduled Maintenance
Cause:
Server timed out while updating a plugin or multiple plugins and left “.maintenance” file undeleted in WordPress wwwroot folder.
Solution:
Navigate, FTPS or SSH into WordPress wwwroot folder and delete ".maintenance " file.
- You have to show hidden files.
If you’re connected using SSH, list wwwroot directory content using ls -a to confirm the presence of “.maintenance” file before deleting.
If you’re using FTP client like filezilla, you have to enable show hidden files and connect using FTP instead of FTPS.
