I've enabled SSL on my WordPress admin pages using
define('FORCE_SSL_ADMIN', true); in wp-config.php. SSL is working now.
However, the "Incoming Links", "WordPress Blog", and "Other WordPress news" sections on the dashboard do not load.
Below is an example of an error I get in the above mentioned sections:
RSS Error: WP HTTP Error: Could not open handle for fopen() to http://wordpress.org/news/feed/
Any ideas what could be wrong?
