This guide explains how to set up a WordPress network of sites to manage multiple sites from a single Infomaniak WordPress installation, with URLs of the type site1.domain.xyz, site2.domain.xyz, or even with domain1.com, domain2.com, etc.

Installing WordPress multisite

To get started:

1. Install WordPress via Infomaniak on your hosting space with a primary domain name:
   
   • This first WordPress site must be accessible and function correctly:
     
2. Connect via FTP.
3. Edit the wp-config.php file of the first WordPress site in question.
4. Above the line "/* That's all, stop editing! Happy blogging. */" (#94), copy and paste the code define('WP_ALLOW_MULTISITE', true);:
   
   
   
5. Save your changes.
6. Then, log in to the administration area of your WordPress site.

8. Go to the TOOLS menu to create a Network:
   
9. Choose the method for creating your different WordPress sites (on subdomains)...
10. Click on the installation button:
    
11. Add the information displayed on the screen to the wp-config.php and .htaccess files on the server.

13. Reactivate your deactivated plugins.
14. In the Manager, add an alias to your website in the format *.your-domain-here (the asterisk allows you to create a wildcard alias) with DNS update so that the correct CNAME is automatically added to the zone:
    
15. Install or update your SSL certificates:
    
16. When you create a new website within the network, for example by naming it home2, it will become accessible via home2.domain.xyz, and so on:
