 * I am not sure when this started or what could have triggered it as I’m just noticing
   it a few days ago, but under site health, I am getting the following error from
   ActivityPub:
 * “Your author URL `https://myauthorurl` does not return valid JSON for `application/
   activity+json`. Please check if your hosting supports alternate `Accept` headers.”
 * I even deleted my website and database, reinstalled WordPress with only the default
   2025 theme enabled, and only had ActivityPub installed and get the same error.
   I’ve also noticed that some platforms on the fediverse are no longer updating
   with my posts which I’m guessing is caused by this error.
 * Please advise.

 * Closing this. I deleted and republished my website and the error went away. Never
   found out what caused it.
