This particular error occurs when WP can’t unzip the .zip file. Check if you have enough space on disc or that you haven’t hit the quota. Also check if you have the permissions for doing such operation. Have you ever updated other WP plugin?
Ya. I update plugins everytime there is a update to it.
Today I was able to update bbpress! no idea why.
Thanks for the response..
And do you know who I can remove the sidebar from my forum: http://technotip.com/forums
