Enable smart user registration across your WordPress Multisite network – allow users with an existing account to register on other subsites using the same email, with subsite-specific role assignment. Fully translation-ready!
By default, WordPress Multisite prevents new user registrations if the email address already exists anywhere in the network. This is a major issue for platforms where each subsite functions as a separate entity – such as coach directories, SaaS portals, multilingual communities, or franchise networks.
Multisite User Registration Fix lifts this restriction by:
– Detecting if a registering user』s email already exists in the network
– Automatically assigning them to the current subsite with a role you define
– Letting you manage roles per subsite from one central network admin screen
– Sending a confirmation email when users are added to new subsites
– Preventing registration errors due to duplicate email conflicts
– Supporting full translation and multilingual setup (via .pot, WPML, Loco Translate, Poedit)
Works perfectly with booking and membership plugins like Amelia, MemberPress, WooCommerce, and more.
