Re: Blog- rss feed
You shouldn't have to know anything about XML to set this up. Normally, clicking on the RSS feed icon of a blog gives you a page that displays the feed content, formatted one way or another — text with tags or formatted text, depending on how your browser handles it. It shouldn't be a bunch of code (do you mean garbage characters?).
All that is needed to set this feature up is to make a new RSS feed on the Admin RSS Modules page with the address gotten from the blog's RSS feed icon, and make a module with that RSS feed to display the feed content. If clicking on the blog's RSS feed icon produces something that isn't recognizable as your blog information and content, then something basic has gone awry. What are the details of your installation? Tiki version, server, etc.?
