Murphy's Law: one week before WordCamp Pisa, my ActivityPub decides to stop working. Thankfully I have no demo but just to talk.
In few words, articles get published very slowly - I must wait several seconds or minutes for them to be published - but they don't federate. All happening since ActivityPub 7.6.x. No other changes.
Deactivated all plugins and problem persists. Before calling hosting provider's assistance I just would like to know what to try next.
As caching plugin, used Wp-Optimize.
