I have installed Feeds 7.x-2.0-alpha7 and Feeds XPath Parser 7.x-1.0-beta3.
After installing this modules i can't find "add article, add page, add poll and other node types on page http://myweb.com/#overlay=node/add
Only posibility add feed and feed item is displayed.
I still can add article by using adress http://myweb.com/node/add/article
but it is not very pretty solution.
