How to make your website to maintenance mode

1. Put maintenance.html into your root directory

2. Open .htaccess file

3. Insert this block in the first line of the file

    ErrorDocument 503 /maintenance.html
    RewriteCond %{DOCUMENT_ROOT}/maintenance.html -f
    RewriteCond %{REQUEST_URI} !(/maintenance.html)
    RewriteRule ^.*$ - [R=503,L]
   

4. Users except you will be redirected to maintenance.html

5. To disable maintenance mode just remove maintenance.html

So what does it exactly do?

ErrorDocument 503 /maintenance.html is when user gets error 503, redirect the page to maintenance.html

RewriteRule ^.*$ - [R=503,L] does rewrite any url without replacing the url and access with 503
