Problem:
The client wanted to translate his logo but he couldn't find the logo URL in "WPML > String Translation"
Solution:
In this particular case, the logo was added by a theme option (Astra theme).
- First, go to the media library to get the IDs of your different logos
- Then go to "WPML > String Translation > Translate texts in admin screens" and search for the ID in the main language
- Add 'site_logo' to "String Translation"
- Last translated ID in String Translation
