The simple membership plugin includes a logout link within the standard login widget. When members are logged into the site, they will see this logout link inside the login widget (as shown in the following image).
Manually Creating Logout Links
If you need to manually create logout links (e.g., to place them in the navigation menu), you can use the following URL:
https://www.your-domain.com/?swpm-logout=true
Replace “your-domain.com” with your actual domain name.
You can create logout links and place them anywhere on your site.
