When you try to upload a file through WordPress, you get the following error:

Unable to create directory /home/USERNAME/public_html/wp-content/uploads. Is its parent directory writable by the server?

To solve this:

1. Go to Miscellaneous Settings in your admin panel
2. The “Store uploads in this folder” will probably have the complete path to your upload folder. Change this to the default value of “wp-content/uploads”. The default value is also mentioned to the right of the same option’s box.
3. Hit save, and try uploading again. This solved the problem for me.
