On a Windows Server 2003 with PHP 5.4.0 a user is trying to use WordPress, but gets the following error when he try to upload something.
PHP Warning: File upload error - unable to create a temporary file in Unknown on line 0
I have tried with a little testscripr to upload, and I get the same error.
upload_tmp_dir is set to f:\temp
I have IUSR and everyone with full acces on f:\temp, so I am kind of lost here.
Anyone with the golden solution?
