Do you post private content? Are you sending those links to your users with private content access?
WordPress by default redirects all non-logged users to a 404(content not found) page when they follow a private post or private page link.Instead of showing a 404 page, this plugin simply redirects those users to the login page.After successful login, it automatically redirects users with private content access to the private content link they followed.
Note: If you post private content and want to get more subscribers to read your private content, I developed a Free plugin for that too…Check out <a href="https://wordpress.org/plugins/mini-membership/" rel="ugc">Mini Membership</a>.

The <a href="https://www.cozmoslabs.com/add-ons/client-portal/" rel="nofollow ugc">WordPress Client Portal plugin</a> creates private pages for each user. The content for that page is accessible on the frontend only by the owner of the page 
after he has logged in.
The plugin doesn’t offer a login or registration form and it gives you the possibility to use a plugin of your choice.
The [client-portal] shortcode can be added to any page and when the logged in user will access that page he will be redirected to its private page.
For login and registration of users we recommend the free <a href="https://wordpress.org/plugins/profile-builder/" rel="ugc">Profile Builder</a> plugin.
You can then use the [wppb-login] shortcode in the same page as the [client-portal] shortcode.
