A newly created blog with widgets plugin and falbum installed, and several themes. When trying to save any of the options pages, I get the following error:
Fatal error: Call to undefined function: http_build_query() in /home/account/public_html/wp-includes/functions.php on line 2430
The server runs on Apache 1.3.36 (unix) and PHP 4.4.2, and the wordpress version is 2.2.4.
What could be causing this?
