WordPress MU

I just completed upgrading my site to the 8-24 nightly build. It went smoothly. But when I test upload an image, I got following error:

The uploaded file could not be moved to .
Warning: Cannot modify header information - headers already sent by (output started at /home/mshao/public_html/wp-admin/admin-functions.php:1931) in /public_html/wp-includes/functions.php on line 1150

Thanks in advance.

I usually get the "headers already sent" because of a blank line after the ?> , regardless if the line number it spews.

This is the "function.php" under wp-includes. I don't see any blank line though.

You're geting the error because WPMU gave you the reason why there's an issue:

The uploaded file could not be moved to

It's kicking out the error before the headers and that messes up the page display.

Sounds like you don't have your file permissions set correctly for blogs.dir and it's subdirectories.

I agree with you. It failed on the line
if ( false === @ move_uploaded_file($file['tmp_name'], $new_file) )

in the admin-fucntions.php. But I examed all the folder permissions for this blog including blogs.dir and wp-content. They all have 777 permission.

Strange!

Check the apache and WPMU error logs.

I got it.
After the upgrade, although cPanel shows that blogs.dir and its sub-directories have 777 permission (inherits from old working copy). Don't trust it. Re-assign 777 to all these folders again.

Hope it help others who have the same issue. Thank drmike and andrea_r for the help.

For some reason, I can't see any words in this thread in my browser. Someone please start a new thread and let me know where this issues stands.
