Given that you have just edited a file and done other things to that skin (copy and delete a folder), change the name of the skin so it can't be used and import a fresh bootstrap_blog_skin to see if the problem still exists.
How do invoke the rss, is it automatic or can you provide the url where you clicked on link?
I don't know how you got to that page with error.

If it works then copy the file before as in the previous topic but do not edit it and see if it works.
Then edit carefully and see what happens
