 * Hello.. I get this fatal error posting!
 * Fatal error: Call to undefined function xmlrpc_encode_request() is coming from
   the server end. I run a php script everywhere on the host server and just get
   this error.
 * I can execute the php script from my locate wamp server to my blog with no problems.
 * Any Ideas?
 * Thanks James

 * `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](http://php.net/manual/en/function.xmlrpc-encode-request.php)
   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](http://www.php.net/manual/en/intro.xmlrpc.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.
