Well here’s one to get into straight away! Recently tried activating Jetpack but had this pop up instead?
Your Jetpack has a glitch. Something went wrong that’s never supposed to happen. Guess you’re just lucky:
Try connecting again.
Error Details: The Jetpack server could not communicate with your site’s XML-RPC URL. Please check to make sure https://icnerd.com/xmlrpc.php is working properly. It should show ‘XML‑RPC server accepts POST requests only.’ on a line by itself when viewed in a browser and should not have any blank links or extra output anywhere.
I’m betting either you have indeed blocked the xmlrpc file (and if you have why would you be here, you know what’s wrong!) or you are using CloudFlare?
Basically the problem is that CloudFlare is blocking access to the URL
Unfortunately the only quick solution would be to disable CloudFlare, enable Jetpack and re-enable Cloudflare. I’m uncertain if Jetpack ever really tries to reconnect via this endpoint however, so i might be the case later that your Jetpack plugin stops working again if you do this.
If you absolutely need CloudFlare enabled, I’d say contact their support and see if there’s anything they can do to help you. Otherwise it might be worth either dropping either Jetpack or Cloudflare as unfortunate as that may be.
I’ll check on this in a month or so to see if there’s anything else out there on this issue! Let me know if you have found any other workarounds! Oddly enough it just worked on one of my sites while testing for this article, but not another site. Very odd behaviour. Just to note I’ve currently tried adding a page rule in to bypass caching/security on this specific URL however that did not resolve the issue. I’ll keep trying! 🙂
