I have a website that uses the Multilingual Press plugin to have more than one language. My question is simple. The languages widget has options to display the flag alone, text alone, flag and text. I need to display the flag and text, but the text is the country language code. For English it displays "en" and for Spanish "es". How do I get it to display "English" and "Espanol" instead? website link movingplanet.info and language switcher is in the footer.
