Each site within a WordPress Multisite network can have its own themes, plugins, and settings. If you want to customize the appearance or functionality of each site separately, it requires additional configuration and management compared to a single site where you only need to handle one set of customizations.
Managing content across multiple sites can be more complex. While there are tools to share content across the network, each site may have unique content needs, and managing these variations can be more time-consuming than managing content for a single site.
Ensuring that plugins and themes work seamlessly across all sites in the network can be challenging. Some plugins may require individual configurations for each site, and themes may need adjustments to accommodate different design preferences for each site.
Keeping a WordPress Multisite network up-to-date requires additional care. Updates to the core WordPress installation, themes, and plugins need to be tested across all sites to ensure compatibility. This can be more time-consuming than managing updates for a single site.
Security practices need to be applied to the entire network, and each site’s security settings may need to be individually configured. This involves more effort than securing a single website.
