The theme is NOT completely WPML ready. Please look at https://wpml.org/documentation/support/achieving-wpml-compatibility-for-your-themes-and-plugins/ . For example, your theme is missing the wpml-config.xml file at its root.
The specific issue I have, is I am trying to translate header settings (phone and email) and footer settings (copyright line). However, WPML cannot find the strings I’ve entered there in the theme, so I am unable to translate them. Please fix this, as we need full WPML compatibility for our bilingual sites. Thank you.
