Thank you for contacting WPML support. While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with the first debugging steps and try to help with the issue quickly.
Can you make sure you are translating the global footer as explained in our docs and via WPML > Translation Management?
Hi Drazen, thanks for your reaction. I translated the Global Footer through the WPML > Translation Management, so that should be ok. I'm guessing the issue is mainly an error in the string translation, when switching to another language.
I managed to resolve the issue, but string translation is often the reason of failure. Translated strings are regularly overwritten by self-generated content by WPML.
