1) Download and install POEdit.
2) Open the “language” folder inside the theme folder and open en_US.po with POEdit.
3) Using POEdit, translate all the strings from the right “Translation” column.
4) Upon saving, POEdit will generate a .mo file (should be in the same folder with the .po file you are editing). Upload that .mo file to the “language” folder of the theme, on your server.
5) Edit your WordPress wp-config.php file and add this line to it, then save the file to server:
define ('WPLANG', 'll_CC');
ll = language code (see list); ex.: pt (Portuguese)
CC= country code (see list); ex.: BR (Brasil)
Reported issues:
– weird characters after translating: make sure you’re editing with POEdit set in UTF8 mode.
