What is WordPress Hook: user_register
The user_register hook in WordPress is a specific action hook that is triggered when a new user is registered on a website. This hook allows developers to perform custom actions or functions when a new user account is created.
Understanding the Hook: user_register

Hook Doesn’t Work: user_register
If the user_register hook doesn’t work as expected, it could be due to conflicts with other plugins or themes that are also modifying user registration processes. To troubleshoot this issue, developers should deactivate other plugins and switch to a default theme to see if the hook functions properly. Additionally, checking for syntax errors or typos in the custom code added to the user_register hook is recommended.
