I got the same problem with you. It seems that there is no option_name ‘rss_language’ in wordpress option table. Let’s take a look file: /wp-includes/feed-rss2.php and file this line:

<language><?php echo get_option('rss_language'); ?></language>

I solved this problem by inserting a new option into wordpress table like this:

INSERT INTO_options(option_id,blog_id,option_name,option_value,autoload) VALUES (NULL, '0', 'rss_language', 'en', 'yes');

Hi DavidPotter,

Add one more record which have option_name: “IWG_RoleMan_Spaces_in_Caps“, option_value: “1” and autoload: “yes” to your wordpress options table.
