Hi,

I want all subscribers to access all posts from the blog only after log in.

I managed to do this by setting  a restriction to the WP_subscriber group but
I need to do this for every post.

Is there a way to set this globally one time and not for everytime I create a
blog post.

Thanks in advance

If I understand you correctly, you can accomplish your goal by setting a Default Category Restriction on the Post Reader role:

1. Go to Restrictions > Category 2. In "Default for all Categories", check the Post Reader checkbox 3. Ensure that Restriction Mode dropdown is set to "Restrict selected roles" 4. Click the Update button

For this usage, you don't need to create any custom role groups.
