ICP Registration Home 404

ICP Registration Home 404 is a lightweight WordPress plugin designed specifically for websites during the ICP filing/registration period.

After enabling:

• Visitors who are not logged in receive a 404 (or 403 / 503) response on the pages you choose
• Logged-in users, allow-listed IP addresses and holders of the preview link can still browse the site normally
• Effectively meets access restriction requirements during the ICP review process

The plugin provides:

• A modern settings panel with a live status overview and a one-click on/off switch
• A “Check as a visitor” button that shows what anonymous visitors (and your CDN) actually get
• A choice of HTTP status (404 Not Found, 403 Forbidden or 503 Service Unavailable) and page: blank page, simple error notice, your theme’s 404 template or custom HTML with a ready-made “site under construction” template
• An allow list: IP addresses and ranges, search engine crawlers (optional) and a secret preview link
• Page hiding by type: front page, blog posts page, single posts, pages, archives, search results or the entire site
• Scheduled auto-close, so protection turns itself off at a time you choose
• Access logging of blocked visits
• Quick toggle in the admin toolbar and the plugins list

Compatible with classic and block themes.

Usage

1. When submitting your ICP filing, pause DNS resolution for the domain
2. After submission, restore DNS and open Settings → ICP Registration Home 404
3. Choose the pages to hide and the 404 response, then save
4. Click Enable protection
5. Click Check as a visitor to confirm the homepage returns 404
6. Once the filing is approved, click Disable protection (or let auto-close do it)

Logged-in users can still access the pages for content management.

External services

This plugin can use the ip.sb IP geolocation service to show where blocked visitors come from. The feature is off by default and only runs when an administrator turns on Show IP Locations in the plugin settings.

• What is sent: the IP addresses listed in the plugin’s access log (never private or local addresses). Lookups are made from the administrator’s browser while viewing the settings page.
• Service: ip.sb – Terms of Use, Privacy Policy
