I've checked your site and found out that this plugin has causing the issue: http://screencast.com/t/4Yi1J6u61tY . I've temporary disabled it and the RSS is working now.
also... while you are at it... can you show me how to fix this url?
before the update, i do not see the "..../component/easyblog..." in the url string, but after the upgrade it now shows... it only shows when you click on the "Latest Updates" link. http://www.bcadventist.com/index.php/latest-updates
