I installed wordpress a while back and then then just left it for a month or so. Now i just logged on today and i have updates for plugins and wordpress itself, when I go to update it asks me for connection information. Also if i want to add new plugins i have to add them through ftp. It wont let me do any of these things through the wp admin panel, what do you think I have done wrong. I figured i didnt change some file permission that should have been changed. Thanks

Here are the things it asks me for.

Connection Information
