Dashboard widgets not working

Hello, the other day I noticed that my Dashboard widgets were not working (or not updating, I'm not sure). I thought it was possibly because I had changed all of my system icons and my dock but after restoring my icons and dock to default the problem still remains. Here is a picture of what my Dashboard looks like:

I've been looking for the solution online and have yet to find it. I also do not seem to have my apple.dashboard.plist file in the Library/Preferences.
If you can help I'll be very thankful!
