During an update, WordPress creates a .maintenance file in the WordPress root directory. If an update is interrupted, the file can remain and visitors may continue to see the scheduled-maintenance message.
- Confirm no WordPress update is still running.
- Open the WordPress root directory in File Manager and enable hidden-file display.
- Locate and remove the
.maintenancefile. - Reload the site and WordPress admin area.
- Review the failed update and complete or retry it only after confirming file permissions and available disk space.
Removing .maintenance clears the maintenance flag; it does not repair an incomplete WordPress update by itself.
