- Logged-in users bypass maintenance mode
- Configurable expected duration (Retry-After header)
- Pre-launch mode for sites that aren’t live yet
- Optional search engine bot access during maintenance
- Bypass link to let non-logged-in users preview the site during maintenance
- Admin bar indicator when maintenance mode is active
- Duration warning after 3 days of maintenance (except in pre-launch mode)
- Returns proper 503 status code for SEO
- Cache plugin detection with admin warning and automatic cache flushing
Requirements:
- WordPress 6.3 or higher
- A block theme (like Twenty Twenty-Five)

How do I create a maintenance template?
-
You have two options:
- Site Editor: Go to Appearance > Editor > Templates, create a new template named “maintenance”
- Theme file: Add a
maintenance.htmlfile to your theme’s/templates/folder
-
Who can see the site when maintenance mode is enabled?
-
All logged-in users can browse the site normally. Only logged-out visitors see the maintenance template. You can also enable search engine bots to bypass maintenance mode, or generate a bypass link for non-logged-in users.
-
What is the Expected Duration setting?
-
This sets the Retry-After HTTP header, which tells search engines how long to wait before checking your site again. Options range from 30 minutes to 1 day. You can also select “Pre-Launch (indefinite)” for sites that aren’t live yet, which disables duration tracking and admin warnings.
-
What is the Bypass Link?
-
When enabled, the plugin generates a secret URL you can share with anyone who needs to view the site during maintenance without logging in. A 12-hour cookie is set on first visit so they can navigate freely. You can regenerate the link at any time to invalidate the previous one.
-
Should I enable Search Engine Access?
-
For short maintenance periods (under 2 hours), the default settings are fine. For longer maintenance (over 2 hours), consider enabling search engine access. For maintenance lasting more than a day, always enable it to prevent pages from being removed from search indexes.
-
What status code is returned?
-
The plugin returns a 503 (Service Unavailable) status with a Retry-After header, which tells search engines the site is temporarily unavailable.
-
Will this work with caching plugins?
-
The plugin detects popular full-page cache plugins (Surge, WP Super Cache, W3 Total Cache, WP Fastest Cache, LiteSpeed Cache, WP Rocket) and displays a warning on the settings page when one is active. Caches are automatically flushed when settings are saved to ensure the maintenance page is served immediately.
Server-level caches (Nginx FastCGI cache, Varnish, Cloudflare, etc.) cannot be detected or flushed by the plugin. If maintenance mode is not working and you use server-level caching, flush that cache manually.
-
How to uninstall the plugin?
-
Simply deactivate and delete the plugin. The plugin stores options prefixed with
pobt_which are removed when you deactivate the plugin.
