How to translate a WordPress theme
We suggest Poedit, to translate Haley Pro theme. It’s available for free on poedit.net.
Open Poedit, go to File > New from POT file and choose haley-pro.pot , under haley-pro/languages/ and choose your native language.
When you’ve finished, upload bot files with your language code (for example it_IT.po and it_IT.mo ), under the language folder of Haley Pro using a FTP client.
Alternately you can install the free WordPress plugin called Loco translate
