xmlrpc.php?rsd shows up blank

Having exactly the same problem… no answers found yet. When I try https://www.paljasken.be/xmlrpc.php?rsd i get a blank page. But with
https://www.paljasken.be/xmlrpc.php I get “XML-RPC server accepts POST requests only.”

I’m also on one.com for my webhosting.

Hi,
You can access your .htaccess when you’re hosted by One.com – but you have to access your webspace through a FTP-client – such as this:
https://filezilla-project.org/download.php?type=client

Then you will be able to tamper with the .htaccess

I had the same issue on all of my blogs, hosted at one.com. After emailing them about the issue, was a technition put on the case that replyed with this fix:

The problem is that WordPress checks if the site can be access through
HTTPS. The script tries to connect to https://thedomain.com to see if it
gets any answer, but does not specify any timeout limit. Our server does
not have any timeout limit for this connection either, so the script
will try for 30 seconds until the whole php scripts times out.

The customer can solve this by editing the file includes/functions.php.
He should find the function called url_is_accessable_via_ssl. In that
function he should add one row so that:

curl_setopt($ch, CURLOPT_URL, $ssl);
curl_setopt($ch, CURLOPT_FAILONERROR, true);

changes to:

curl_setopt($ch, CURLOPT_URL, $ssl);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
Med vennlig hilsen / Best Regards
