I’ve been blogging using XML-RPC for years.
In less technical terms, I’ve been blogging by finding a suitable photo on Flickr and selecting ‘blog this’.
This then generates a draft blog WordPress posting that I can polish off and post.
However, when I migrated to eUKhost, it suddenly stopped working.
After wasting a lot of time digging into the problem, I realised that Flickr was getting a 404 error when sending a POST request to xmlrpc.php.
In other words, there was nothing I could do myself, so I contacted eUKhost’s support, and they promptly created an exception for this file in mod_security, which was all it took for everything to be working beautifully again!
It seems eUKhost are a bit paranoid about security (which can be a good thing!), but they’re also very prompt and helpful.
