How can I translate the result-page for the search function?

Please use Codestyling: http://wordpress.org/plugins/codestyling-localization/ to translate the theme text strings. Install the plugin, go to Tools > Localization and select “Themes”. Then search for “Enfold” in the list and click on “Add new language”. Then select your language from the list and click the “create po-file” button. Click on “Rescan” to fetch all text strings. Then click on “Edit” and translate the required strings from the “avia_framework” textdomain. At least click the “create mo file” button next to the “Textdomain” selection dropdown (top left corner).
