Console Error. Please Help

I recently updated my CraftBukkit to 1.4.6 so my friends can join and have fun you know? But now, I am getting this weird console error. I don't know why. Look at the code. The error begins after it says "done." But some errors can be seen before it says "done." Like these. VVVVV

Console Error:

Update disguisecraft, update heads, update essentials, update worldguard

 

This error just keeps getting spammed in the console.

 

Update Essentials, WorldGuard, Disguisecraft and Heads. Use the development versions if available.

Edit: Never realised someone had already posted. Sorry.

 

Because they are "Outdated".

 

Best to just update all of your plugins and make sure you are on the lookout for new ones all the time. That way you wont have as much plugin problems and EVEN less lag.
