Sorry for the trouble. Are you using it in combination with the Friends plugin and can you see the posts there?
Yes. Everything on the website is working perfectly.
Hm, can you see the posts for the timeline endpoint in the Mastodon API Tester?
Only posts from site users.
If you go to wp-admin/options-general.php?page=enable-mastodon-apps&tab=registered-apps (i.e. Settings > Mastodon Apps > Registered Apps), and click on Details of your app, under “Show these post types” do you have both “Posts” and “Friend Posts” selected?
Hm. I wonder if an other plugin could be interfering, do you have many others?
No. This is a website to test that Friends theme that Lívia is working on. It only has Health Check, ActivityPub, Enable Mastodon Apps, Friends and the plugin with the theme. If you want to take a look directly, I’ll create a user for you. I sent you a message on Matrix. Thanks for the quick responses!
