Theme translation not applying

Question

I donwloaded and applied a theme to my WordPress 4.7.2 installation.

The site's locale specified in the admin settings is it_IT and the theme was not translated in this language so I'm trying to create a translation for the custom strings the theme uses.

So what I did was:

• Opened the /wp-content/themes/thf/languages/thf.pot file (thf being the theme's name) with POEdit
• Created a new it_IT translation and translated all the strings
• Saved the project. /wp-content/themes/thf/languages/it_IT.po and /wp-content/themes/thf/languages/it_IT.mo files were created
• Edited the functions.php adding the following.

.

function thf_setup() {
    load_theme_textdomain( 'thf', get_template_directory() . '/languages' );
}

add_action( 'after_setup_theme', 'thf_setup' );

But the strings won't translate. Looks like I don't need to define WP_LANG in config.php since I'm on WordPress 4.7.2 so I didn't edit that.

I also looked at other similar questions but they all point to either load_theme_textdomain, which I added, or WP_LANG, which I don't need.

Am I missing something else? Thanks in advance for your attention.

Answer 1

The problem was more trivial then expected.

The function thf_setup() was already defined and hooked in the theme's functions.php so I just added the load_theme_textdomain call to that function instead of declaring a new one (which would also be duplicated).
