Problems with updating widgets

Hi all, I’ve run into a very frustrating problem regarding updating widgets both in my sidebar and footer. Every time I try to update something, say with the text widget or any widget, and I refresh the page, nothing happens. It still stays the same as it was before. If I re-order the widgets by dragging and dropping, the same thing nothing happens. This just started happening this evening. The most recent plug in I installed was the slickr flickr plugin and that too won’t update. I tried installing/deactivating; nothing works. The only way I found I could get the widgets to update is if I went to each page one-by-one and actually hit “update” on each page. Then when I’d refresh, it would work. But clearly this isn’t normal.

I’d really appreciate anyone’s help into this annoying matter!
