Localization issue. Codestyling localization, incompatible theme

I haven’t seen all files in your attachment, some directories are not included, so this is just a guess:

1. Create a directory languages in the theme for the language files.

2. Add the following to the style.css header below License URI:

    Textdomain:  jobroller
    Domain Path: /languages
   

3. In functions.php add:

   add_action( 'after_setup_theme', 'jobroller_load_language' );
   
   function jobroller_load_language()
   {
       load_theme_textdomain( 
           'jobroller', 
           get_template_directory() . '/languages' 
       );
   }
