All our themes are fully translatable and here's the guide to be able to translate the theme yourself. First, you will need to download PO FILE EDITOR then install it on your computer. Next is to open the default PO File language/themename.po of the purchased theme using the PO FILE EDITOR then simply select the text you want to translate and then type the corresponding translation on the big text area found on the bottom most part of the POEdit application.
Notice that when you type something on the text area, the Translation column will populate the text you entered on its corresponding original text. Now next is to save the file to corresponding country code like en_US if US or fr_FR if France or desired filename if you want, save it into the same directory.
Next is to open wp-config.php file located at the root directory of your WordPress and find the code below.
define ('WPLANG', '');
replace with …
define ('WPLANG', 'the filename of the PO FILE created without .po extension');
