upload.php not found

I just recently uploaded wp and everything seems to be working well except i have found this.

In my admin area on the write tabs i have an error.
“Not Acceptable
An appropriate representation of the requested resource /blog/wp-admin/upload.php could not be found on this server.”

I have also noticed that I don’t have a way to upload pictures like on my profile page.

Are the 2 connected and how do i fix it?
