RSS Feed has errors

At first this error was on and off for months. Now it hasn’t worked for over a month. When it doesn’t work, I can’t post to my Facebook and Twtter feeds.
The feed validator says it works, but still has errors.

I really don’t know how to use SSH. I’ve installed Putty SSH to my PC, but I still don’t understand exactly how it works. I’ll eventually read and learn about using SSH, but my main priority is to fix the RSS feed. I will turn it off, but I really need it to work for my site’s subscribers. If there isn’t a simpler solution, I will appreciate more help from you or someone from the forum to guide me through the Dream wiki solution step by step.

Also, if you prefer movies, you should try YouTube. There are thousands of video tutorials there. I’m sure there will be at least a few on ssh.
