I can't modify footer 02

Hello @alfredotonelli,

Here I send you the online document of this theme.
I also wrote clearly for this part. You have to set in WP Bakery Page Builder. Please see then Big Note then try it for your site

If you have other questions, do not hesitate to contact with me.
Could you go here: http://themeforest.net/downloads then rate me a good review + 5 stars please? It's really very worth with me.

Thank you very much!
Best regards,
Yame
