Finspire Creative

This plugin prevents logged-in users from viewing the Ultimate Member core Login page. If a logged-in user visits the UM Login page, they are redirected to a URL you control in Settings → Login Redirect for Ultimate Member.
Key features: 
* Redirect logged-in users away from UM’s core Login page 
* Admin settings page to configure the destination URL 
* Works with internal paths only (e.g., <code>/home/</code>) 
* Safe behavior if Ultimate Member is not active (shows an admin notice; can auto-deactivate)
