Unable to create directory wp-content/uploads/2013/08. Is its parent directory writable by the server?

Hello I have been trying to upload an image into my Wordpress dashboard without success. Every time I try to upload the image, I get an error like below:

Unable to create directory wp-content/uploads/2013/08. Is its parent directory writable by the server?

I am using CentOS 6.4 with latest Wordpress. My WP is located in /dir1/dir2/dir3/wordpress, and below this, wp-content has “uploads” directory and within this 2013/08 directories. Additionally, I had to create uploads/2013/08 as they did not exist in the original installation process following the instructions from DO. I have changed permission and that too did not work. Same upload error shows still.

This is what I do to see the error from Wordpress:

1. Dashboard --> Pages --> ‘Add Media’
2. Dashboard --> Media --> ‘Add New’

As mentioned, uploading an image shows the error stated above regardless of which image I choose. I have not had any problem installing themes or plugins, just the problem with image upload.

I have rebooted my host, also, and retired image upload without success.

My host has LAMP (CentOS) and WordPress.

Please could you suggest a fix for this kindly.

Thank you.
