Blank screen @ wp-admin

Hello folks,

This is my first post on these boards. Anyhow, i installed few plugins yesterday and now I can’t access to my wp-admin anymore. It only show blank screen…

I did some research and found out that the problem might be caused by functions.php file. However, I’m not a “tech” guy so it’s pretty hard to find the solution.

Here is the uploaded version of my functions.php: http://www.upload.ee/download/3021130/205aa517a38c98bd2be/functions.php

Maybe someone can help me to fix that, or give me some suggestions…

Thanks!

looking forward.
