RSS feeds in Dashboard broken

I recently imported my WordPress press blog from one to the other. I had some issues that were slowly fixed. My last problem is that when I go to the dashboard, I see nothing in the ‘Incoming Links’, ‘Plugins’, ‘WordPress Development Blog’ and ‘Other WordPress News’ panels all showing nothing. When i configure them, they all show correct, valid links but nothing ever shows up.

Does anyone have a clue what the problem might be?
