Hi ShivatZion ,
Thanks for reaching out to us!
Unfortunately, Buttonizer currently doesn't fully support multi lingual plugins such us WPML.
Although, you can maybe use Page Rules instead to show a different label and run a different button action per language.
For multiple languages, I would for example, create 2 buttons.
One button redirects to an English page and the other redirects to a French Page.
I would then use page rules to make those button only appear on the correct language.
We have a step by step tutorial on how to use page rules to make those buttons appear on their respective pages on this topic:
