# Fatal error: Call to undefined function: xml_parser_create()

 * Then submitting a post I’m getting the following error message:
 * [quote]Fatal error: Call to undefined function: xml_parser_create() in /htdocs/
   www/wp-includes/class-IXR.php on line 144[/quote]
 * The posts get, well, posted, okay, but I’d like to get this sorted out since 
   I’m going to be using WP as a content management tool and any kind of fatal error
   message is likely to cause a few heart attacks. I’d like to steer clear of real
   fatalities!

 * That should be “When submitting a post…”
 * Any ideas?

 * The function xml_parser_create() is a PHP function, which would lead me to believe
   that your installation of PHP either isn’t complete or is corrupted somehow.

 * I’d found that post in searching the forums looking for a solution, but I confess
   I had no idea what the final post meant when it said:
 * > I had exactly the same problem. Solved by re-emerging php with the ‘xml’ flag
   > set (in /etc/make.conf)
 * I couldn’t figure out what file (/etc/make.conf) he was talking about, and don’t
   know what “re-emerging php with the ‘xml” flag set” means!
 * Any pointers?

 * I think “re-emerging” was meant to be re-compiling. Unless you’re self-hosted
   or have full control over your server, you’ll have to contact your provider and
   ask if they can set up PHP with xml support.

 * That’s exactly what it turned out to be, and with the help of my webhost it took
   about 30 seconds to sort out. Many thanks!
