1. Does this work with any WordPress theme?

Yes! It works with all themes including Astra, Divi, GeneratePress, Block Themes, etc.

2. Does it affect SEO?

Both modes send a 503 (Service Unavailable) response with a Retry-After header, which tells search engines the downtime is temporary. You can change the status code with the scsmm_status_code filter.

3. Can I allow only certain people to access the site?

Yes. You can allow:
– Logged-in administrators
– Selected IP addresses, IPv4, IPv6 and CIDR ranges (e.g. 203.0.113.0/24)

4. Does it block the REST API?

Optional. Enable Block REST API in the Access tab to stop published content being read via /wp-json/ for visitors while the mode is active.

5. Does the plugin collect or store any data?

The plugin itself does not track users or collect analytics.

If the Local email provider option is enabled, subscriber email addresses entered in the Coming Soon / Maintenance form are stored in the site’s WordPress database. This data is stored only on your website and is never sent to any third party.

You can view, export (CSV) and delete subscribers under Standby → Subscribers. All plugin data is removed when the plugin is deleted.

6. Will this slow down my website?

Not at all — the plugin is extremely lightweight and optimized.

7. Does the plugin support video backgrounds?

Yes. MP4 and WebM video backgrounds work in all three templates. The background image is used as the poster/fallback, and the video is not shown for visitors who prefer reduced motion.

You can upload or select an MP4 video from the WordPress Media Library and use it as a background. For best performance, it is recommended to use optimized, short-length videos and avoid very large file sizes.

8. Can I whitelist IP addresses?

Yes. You can add specific IP addresses to a whitelist.

Visitors coming from whitelisted IPs will be able to access the website even when Coming Soon or Maintenance Mode is active.

New
* Subscribers screen (Standby → Subscribers): view, export to CSV and delete locally stored subscribers.

Fixed
* Subscribe form did not work in the Minimal template.
