Overview of the Issue
In the Botiga theme, texts that you type in the Customizer, like the footer credits, show in the default language on translated pages. They do not appear in WPMLString Translation.
Workaround
Until Botiga fixes it, register the text in WPML:
- Go to WPMLString Translation and click Translate texts in admin screens at the bottom of the page.
- Find
theme_mods_botiga, selectfooter_credits, and click Apply. - Go back to String Translation and translate the footer credits.
