I see it all in the en_US files, but when i open them in PoEdit and translate them, change the settings to nl_NL and then upload them in wp-content/languages/themes/fitpro-nl_NL.po and .mo they don’t work, which should.
Also tried in the childtheme folder/languages/nl_NL.po & .mo but they don’t pick up there as well.
Are you sure the theme is using it’s i18n functions right?
load_theme_textdomain in framework.php referes to a locale.php file. But shouldn’t that be a .mo file?
Please check this, as I still can’t make it show up.
Well that doesn’t add any value to this conversation as I already mentioned I tried that, no luck! Using a childtheme – tried in both parent and childtheme /languages folder as nl_NL.po and nl_NL.mo – did that work for you then? (with my files?)
