Frequently Asked Questions
Common questions about ActivityPub
ActivityPub for WordPress adds Fediverse features to WordPress, but it is not a replacement for platforms like Friendica or Mastodon. If you're looking to host a decentralized social network, consider using Mastodon or Friendica.
The name ActivityPub comes from the two core ideas behind the protocol: Activity: It is based on the concept of activities, like "Create", "Like", "Follow", "Announce", etc. These are structured messages (usually in ActivityStreams format) that describe what users do on the network. Pub: Short for publish or publication. It refers to the fact that this is a publish-subscribe (pub-sub) protocol — one user can "follow" another, and receive their published activities. Put together, ActivityPub is a protocol for publishing and subscribing to activities, which enables decentralized social networking — where different servers can interact and users can follow each other across the Fediverse.
We have a How-To section in the docs directory that can help you troubleshoot common issues. Constants The plugin uses PHP Constants to enable, disable or change its default behaviour.
