Each website is set up as usual through the Multisite management, regardless of whether your network is based on subdomains or subdirectories. Using the site ID automatically assigned by WordPress, the plugin then connects each website to its own, freely chosen domain.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\">Whether it&#8217;s automatic HTTPS, clean redirects, or managing multiple domains: the plugin was built specifically for the needs of professional Multisite environments.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\">On this page, you&#8217;ll find a detailed overview of the technical requirements, the core features in detail, as well as advanced features and compatibility information \u2013 so you know exactly what to expect before installing.<\/p>\n<\/div><\/div><div class=\"w-separator size_large with_line width_default thick_1 style_solid color_border align_center\"><div class=\"w-separator-h\"><\/div><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2>System Requirements<\/h2>\n<p>For Onartline Multisite Domain Mapping to work reliably, the following requirements must be met:<\/p>\n<h3>WordPress Multisite Network<\/h3>\n<p>The plugin requires an activated WordPress Multisite installation. On a single WordPress installation (single site) without an active network, the plugin cannot function, since domain assignment is based directly on the site ID assigned by WordPress within the network.<\/p>\n<ul>\n<li><strong>WordPress version:\u00a0<\/strong> Mindestens WordPress 7.0 or higher is required.<\/li>\n<li><strong>PHP version:\u00a0<\/strong> PHP 8.3 or higher is required. For details on supported PHP versions, see the <a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" title=\"Official PHP supported versions\" href=\"https:\/\/www.php.net\/supported-versions.php\" target=\"_blank\" rel=\"noopener\">official PHP supported versions page<\/a>.<\/li>\n<\/ul>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>Write permissions in the wp-content directory<\/h3>\n<p>For the automatic installation of the <code>sunrise.php<\/code> file, the plugin needs write permissions in the <code>\/wp-content<\/code> directory. If these aren&#8217;t available, the plugin will notify you during activation and let you continue the installation once permissions have been temporarily adjusted.<\/p>\n<\/div><\/div><div class=\"w-separator size_large with_line width_default thick_1 style_solid color_border align_center\"><div class=\"w-separator-h\"><\/div><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2>Core Features in Detail<\/h2>\n<h3>Domain Assignment (Domain Mapping)<\/h3>\n<p>Every website within your Multisite network can be assigned its own, custom domain. Assignment is based on the site ID provided by WordPress and can be conveniently set up, changed, or removed through the network admin \u2013 with no need to touch the database or write code.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>Automatic HTTPS<\/h3>\n<p>Once a domain is assigned, the plugin ensures all requests go through a secure HTTPS connection. This requires a valid SSL certificate to already be in place server-side for that domain \u2013 the plugin itself doesn&#8217;t issue a certificate, but ensures HTTPS is correctly recognized and enforced within WordPress.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>301 Redirects<\/h3>\n<p>For cases where an old address should permanently redirect to the new, assigned domain, the plugin supports permanent 301 redirects. This is especially helpful for preserving existing search engine rankings when a website moves to a new domain.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>Site Administrator Management<\/h3>\n<p>Optionally, the Super Admin can grant individual site administrators permission to manage their own website&#8217;s domain assignment themselves, without requiring network admin intervention every time.<\/p>\n<\/div><\/div><div class=\"w-separator size_large with_line width_default thick_1 style_solid color_border align_center\"><div class=\"w-separator-h\"><\/div><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2>Advanced Technical Features<\/h2>\n<h3>Cron Job Support<\/h3>\n<p>Onartline Multisite Domain Mapping runs an automated check every hour in the background: expired login tokens are cleaned up, and all domain assignments stored in the network are checked for reachability. This check runs network-wide and isn&#8217;t tied to a single website \u2013 so it works whether you use WordPress&#8217;s built-in WP-Cron or set up an external server cron instead. For higher-traffic websites, we recommend replacing the built-in WordPress cron with a real server cron job, since it&#8217;s more reliable and resource-efficient, regardless of whether visitors are currently active on the website.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>Object Cache Compatibility<\/h3>\n<p>The plugin is compatible with common object cache solutions (such as Redis or Memcached). This caches frequently requested domain assignment data, further improving load times \u2013 especially in Multisite networks with many assigned domains.<\/p>\n<\/div><\/div><div class=\"w-separator size_large\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2>Compatibility and Deployment Recommendations<\/h2>\n<h3>Tested Hosting Environments<\/h3>\n<p>Onartline Multisite Domain Mapping has been successfully tested with common hosting panels such as Plesk and cPanel. When using such panels, keep in mind that they may have their own redirect features active (e.g., &#8220;Preferred Domain&#8221; in Plesk) that can overlap with the plugin&#8217;s redirect functions. In this case, we recommend disabling either the hosting-level redirect or the corresponding plugin feature to avoid redirect loops.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>Object Cache Systems<\/h3>\n<p>The plugin is compatible with the common object cache solutions Redis and Memcached and benefits from their caching when processing domain assignments.<\/p>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h3>New Multisite Installations<\/h3>\n<p>Onartline Multisite Domain Mapping is designed for use in newly set up Multisite networks. Deploying it in an already active, production Multisite network is not recommended.
