Hi,

As 1st step, install FR translation. You can do it from SPPB or by using FTP tool from below package

FR-SPPageBuilder_UNZIP.zip

It was made by commuity, so not all areas may have translation.

Thank you , but how can i change the label from add-on contact in french.

Those phrases should be translated inside above files.

I recommend reading tip "How to translate contact form" from >> https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/how-to-tips

(easy english, Google translator should help you)
