How to fix WordPress and Ulysses publishing errors

When I try to publish my posts from Ulysses application I get the following error message.

The solution for this is to install a plugin called Rename XMLRPC. Below are the steps I took to fix the issue

  1. Login to your WordPress hosting site and access the File Manager and locate your XMLRPC.PHP file. You will find this file under public_html folder
  2. Download a copy of this file, just in case if you ran into any issues you can restore it.
  3. Now, rename the file to what ever you like. I renamed it to xmlrpc_20240317_orginial.php
  4. Install the Rename XMLRPC by going to to your WorkPress plugins section and click on Add New Plugin and in the search bar type Rename XMLRPC and locate the plugin and click install.
  5. Next, click on the Plugin File Editor and you see a working Heads Up! click on I understand. Then from the Select plugin to edit dropdown select the Rename XML RPC and click Select
  6. Locate xmlrpc.php and replace with the name you choose to rename in the step 3. In my case I renamed it to xmlrpc_20240317_orginal.php and click Update File. It the one 14 in my below screenshot.
  7. Go back to Plugins and click on Installed Plugins and find the Rename XMLRPC plugin and click Activate
  8. Finally now jump back to Ulysses application. Select any of your post and click publish to WordPress. There you type your WordPress url.
    1. https://yourdomain-name/xmlrpc_20240317_orginial.php
    2. It will ask you to login into your WordPress account.
  9. That’s it you are done.
