Error cannot write

[Guest]

I get the following error:

 

Error: I can not write to this file. Please set the right user permissions on: /home/rragsnao/public_html/litsales/osCommerce/catalog//.htaccess

 

I have searched the knowledge database, I have followed the instructions. I have changed the permissions.

 

I still get the error.

 

I am at a loss
