Problem displaying the theme when importing a wordpress site locally with wamp.

Hello,

I am a developer who has to modify a WordPress site made with a DIVI theme (Address of the site: a3aconception.fr). I want to import the site on a local server on my computer with Wamp to have a copy of the site offline to work on. I believe to have succeeded well the importation of the database as well as the site in itself but in spite of that when I launch the site in local, the theme does not display correctly at all. For example, the design of the menu is completely changed and the logo of 'DIVI' added (as if the theme was reset). However, I recovered the backup file of the site thanks to Jetpack and thus recovered the theme. I put you in attachments the display of the basic menu and therefore the one I get when I import the site locally to give you an example. Maybe someone has already encountered this kind of problem. In any case, thank you in advance for your answers.
