Need a WordPress master to fix the "missing temp folder" error

I have tried about 30 fixes for the error I am receiving in WordPress when trying to upload an image.

The WordPress install is new and theme, and themes required plugins are installed. The website is hosted with Yahoo small business.

Things I have tried:

• deactivate unnessary plugins
• add this line of code to wpconfig file and create the needed folder

• changed permissions of the folders to 775
• and just about every other f**king thing I can think of or read about
• tried reinstalling WordPress and installing into a new directory
• calling Yahoo for help

I was hoping someone could team viewer in to my computer and have a look at the issue. Any takers and what is your price?

Hello,
try one thing, go to admin dashboard > settings>media
and see if you have any path there. if you see what is that path?

when you installed wp did you use one of the auto installers or upload the files yourself and set it up

If you did all the things in their why don't you try to move your host to somewhere else...
As far as i know yahoo hosting is sucks
