I just found out my site was broken all day for un-logged-in users (i.e. everyone but me).

The homepage was fine, but clicking through to the most recent top post resulted in this error. Other posts were fine.

I disabled the #wordpress #activitypub plugin and things started working again.

cc @pfefferle any ideas?

@jan this is most likely because of caching? do you have a caching plugin in place?

can you configure your caching plugin, to use different buckets based on the Accept header?
