Symbolic link for uploads in wordpress

You will need to ensure that your web server has symlinks enabled. For Apache2, this is Options FollowSymLinks. For Nginx, the option is disable_symlinks off;. If you are not using either of these, you may need to consult your servers documentation.

If you are you using a web hosting provide, you can also see if there is an option in their dashboard. If not, you may need to contact their support team to see if they can help you.

Also, make sure that your filesystem permissions are correct. You may get a permission denied error if they are wrong.
