RSS feed not working

I’ve read some of the previous posts from others having trouble with their RSS feeds and followed their suggestions to return to the permalinks to default settings in the hope that this would solve the problem…it did not.

I’ve tested this RSS problem using both Internet Explorer 8 and Google Chrome (just in case this was a browser issue) and the problem persists. I’m new to WordPress and do not know how to write code myself. Here is my site so you can view the problem (the RSS is on the bottom of the page). http://livingwithinvisibledisabilities.org I would appreciate your help.

Thank you.
