@manton I've been able to verify that the problem is with all webmentions, not just those coming from Micro.blog or any other subset of them. When I run at test like the one at webmention.rocks it says my webmention endpoint returns an invalid HTTP status code when mentions are attempted to be sent. Other than this my WP installation works fine, so it's really confusing to me. Anyway, thank you for looking into the logs for me.
@manton Thank's for the reply. It seems like webmentions has stopped working on my site since I moved from shared hosting to my own VPS. I'm trying so sort it out now but I'm completely out of ideas.
Just as a long shot, you don't happen to know about some fiddly setting or something that will cause WP to responde 500 to an attempt to send a webmention?
It seems like my site has lost the ability to receive webmentions since I moved it to my VPS. I wonder that the F is going on…
