hi guys Im back, theres only 2 plugin installed its the http://wordpress.org/extend/plugins/wp-db-backup/

I cant really figure out on what happen on the website, but what I did to fix this weird problem ,...is I reinstall wordpress , (upload the new copy of wordpress on the site, and I make sure its latest one) - equivalent to a manual update.

After that its started to work fine... so this problem is now fixed...

You're going to need to provide quite a bit more information, about your environment (WordPress version, active Theme/Plugins, etc.), anything out of the ordinary that you might be doing, and where/how you're getting the error. – Chip Bennett Aug 12 '11 at 18:12

Check WP Error Fix (wordpress.org/plugins/wp-bug-tracker) plugin. I guess it was called WP Bug Tracker before. – user41007 Oct 28 '13 at 12:24

wp() is quite essential function. It resides in functions.php file (don't confuse with functions.php in theme, different thing) and I don't think you can load WP without passing require directive for that file at some point.

So your install seems very broken - either functions.php file in core is damaged or something else is broken and makes it skip loading that file.

yes your right man , what I did is I reinstall everything...I fix the problem already before I read your answer, but your answer is same as mine , so I'll pick your answer too :) – arnold Aug 14 '11 at 5:08

This problem can be caused by using the automatic update when you don't have enough disk space. If that is the case, free up some space on your server, then upgrade Wordpress to the latest version manually.
