WishList Member includes the option to either enable or disable WishList Member from handling the After Login and After Logout Redirects.
The settings are located in the Advanced Options > Logins section in WishList Member.
Enabling “Allow WishList Member To Handle Login Redirect” will allow WishList Member to handle the After Login Redirect.
Enabling “Allow WishList Member To Handle Logout Redirect” will allow WishList Member to handle the After Logout Redirect.
Disabling either of these options will allow the potential for another installed plugin to handle the After Login / Logout Redirects.
