We have just implemented a server wide block on xmlrpc.php.
This has been done to stop denial of service attacks occurring with WordPress sites hosted on bibly. It is a temporary measure as we work our way through each site and put preventative measures in place per account.
XMLRPC is used by some WordPress plugins and if required some site functions may not work as expected. Please contact us via firstname.lastname@example.org or by submitting a ticket here if your site is experiencing any issues as a result of this change
