Descrição
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.

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

Perguntas frequentes
-
Will this affect search engines?
-
The plugin is intended for temporary use during ICP registration. Simply disable it after approval.
-
Will it affect the admin area or other pages?
-
No. It only affects the selected page types for visitors who are not logged in. The admin area and the login page are never blocked, whether protection is on or off. Front-end login pages from themes or plugins (such as Zibll’s
/user-sign) are detected and kept open as well, and you can list other always-open pages under Admin and Login Pages. -
Is cache/CDN supported?
-
Blocked responses are sent with no-cache headers and the
DONOTCACHEPAGEflag. When you switch protection on or off, the page cache of popular caching plugins is purged automatically. A CDN cache has to be refreshed manually. Use Check as a visitor to confirm the result. -
Which response should I choose?
-
404 Not Found is the most common choice during ICP filing. 503 Service Unavailable tells search engines the site is temporarily closed, so they retry later instead of dropping indexed pages. For the page, Blank Page reveals nothing and is the safest choice during the review. Theme 404 Template looks nicer but may still show your site name and menus.
-
What is custom page content?
-
You can provide your own HTML for the blocked page: either a complete HTML document, or just the body content. It starts from a “site under construction / undergoing ICP filing” template, and an empty field uses that template too.
-
How do I let my own computer or office through?
-
Add your IP address or range (such as
198.51.100.0/24) to the IP Allow List. The settings page shows your current IP with a one-click Add to allow list button. If your site sits behind a CDN or reverse proxy, also turn on Site Uses a CDN or Reverse Proxy so the real visitor IP is used. -
Yes. The admin area and login page are never blocked. Turn on the Preview Link and open it on any device: it lets you browse the site normally for 7 days. Create a new link at any time to make the old one stop working.
-
Should I let search engine crawlers through?
-
Only if you need to keep the site indexed. Crawlers are recognized by their User-Agent, which can be faked, and showing crawlers different content than visitors may be treated as cloaking by search engines. If you mainly want to keep your rankings, 503 Service Unavailable is usually the safer choice.
-
What is access logging?
-
When enabled, the plugin logs blocked access attempts including time, IP address, URL and user agent. Maximum 100 entries are stored.
-
How does auto-close work?
-
Set a time and the plugin turns protection off automatically, using the timezone in
Settings → General. This is useful to avoid forgetting to disable it after ICP approval. -
Can I hide other pages besides the homepage?
-
Yes. You can hide the front page, blog posts page, single posts, pages, archives and search results independently, or the entire site.
-
Can overseas visitors keep seeing the site?
-
Yes. Turn on Let Visitors Outside Mainland China Through: only visitors from mainland China are blocked. The country comes from a header your CDN adds (Cloudflare’s
CF-IPCountryby default; other CDNs can be configured). Requests without the header are blocked, so only use this when all traffic passes through that CDN. -
Which page looks the least suspicious to a reviewer?
-
Many site owners prefer Nginx Error Page or Apache Error Page: they reproduce the web server’s own default error page, as if no site had been deployed yet.

2.4
- New: optionally block mainland China visitors only, using the country header from your CDN (Cloudflare’s CF-IPCountry by default), so overseas customers and search engines are unaffected
- New: Nginx and Apache default error page look-alikes

- New: with the entire site hidden, the REST API is blocked for visitors too, so posts can’t be read through /wp-json
