Call to undefined function xmlrpc_encode_request()

xmlrpc_encode_request() is not used, as far as I can tell, in the current version of WordPress, so it may be in a plugin. Try deactivating your plugins until you find the culprit. The PHP documentation for this function includes a warning about the experimental status of this function, and it sounds like your host doesn’t support it.

Hi Jeremy…. Thanks for your feedback on this function. I am just puzzled, why if I send a post to my blog from a remote computer with the same php scipt it works perfect. It should crash all the time with this function call. I have sent it from many computers with the same php code all works. Just cannot use this script on the host server. I am trying to setup cron jobs with this script. Is there any (alternate) function I could use to simulate this xmlrpc request.

Thanks again
James

Whether the script works or not will depend on whether the server you are running it from supports xmlrpc_encode_request(). You said earlier:

I can execute the php script from my locate wamp server to my blog with no problems.

This sounds like your local wamp server has or supports xmlrpc_encode_request(), and likely other things in the XML-RPC extension for PHP, while the other servers where your running your scripts do not.

There likely are other alternatives to this function. I recommend consulting the PHP documentation for the function, which I linked to in my previous post.

If you think you should be able to use the XML-RPC extension on your server, you should contact you server administrator or host for support, because this doesn’t sound like a WordPress-specific issue.
