Forbidden 403 error, permission to access, unable to read htaccess

Your .htaccess is not readable (like the error noticed).

So make your .htaccess readable using permission 644. Source

Now check again, perhaps now your stylesheet will be loaded?

If not, check if the stylesheet file is readable.

May this not be the cause, check the owner of the files.
