This thread is resolved. Here is a description of the problem and solution.
Visiting product page or a page where currency switcher is present, could produce an error with WooCommerce Multilingual v 4.7.0
To fix the issue, you can just go to WooCommerce > WooCommerce Multilingual > Multicurrency and edit the currency switcher settings.
You should just change the template that is used and save. Then you can return the template to its previous value, and the error should be resolved.
