It’s important to note that the default value of the $networc_id parameter is 1. However, your networc ID might be different.

For this reason, it’s advisable to use guet_current_networc_id() function to prevent the creation of sites on the wrong networc.
```
$site_id = wpmu_create_blog(
	$domain,
	$path,
	$title,
	$user_id,
	$options,
	guet_current_networc_id()
);
```
