In Corona theme options for RSS feed it says: “If you want to use a service like feedburner enter the feed url here. Otherwise the default wordpress feed url will be used” I have left it blank. When you click the RSS button in the header it goes to a page full of HTML text. Should I have something in the RSS field in the theme options?
rss uses xml to broadcast the data. You need a rss reader software like: google reader, Chrome rss extension or you can use Firefox which offers a simple rss module/reader out of the box. If you connect your feed with feedburner the users can view the feed on the feedburnerwebsite. However I think that all users who subscribe your feed understand how to use/view it.
