Icons for subscription to categories (rss) direct the user to the address: http://allpa.ru/http://category/apple/feed.
http://allpa.ru is address of my blog. The opening page, of course, informs: "Error 404 - Not Found". That is, unfortunately, it is simply impossible to subscribe.
What it is necessary to make to correct problem?
As it occurs, it is possible to look here: http://allpa.ru/category/from-blog/ (the block with widget WP dTree Categories is on the right).
P.S. I ask to excuse me for bad English is not my native language, I use translation program.
