Permissions warning when creaitng invoice

When I try to edit an existing invoice or try and create a new one I get a permissions warning. Never had this before.

Warning! The plugin can’t create pdfs in the folder /homepages/9/d4297655757/htdocs/wordpress/wp-content/uploads/rednao_wcpdfi/attachments/ please fix the permissions of that folder or we won’t be able to email invoices

So I have updated the permissions on the attachments folder – gave it full permission to Read, Write and Excuse – code 777 but still get error message.
Never had this on other sites that use this plugin.
