Can you please have a look at the “Site Health” page of your WordPress installation?
It says that there’s no site cache and that the server is slow
I have now WP Super Cache running but no luck. Any idea what I can do?
user-agent ‘Go-http-client’ was used on my server because it is often used by malicious botscans and attacks. now that it’s activated again the Webfinger is fine but it still doesn’t show up in Mastodon. what else is still going wrong here?
