Visual Composer is not working anymore

Hello,

I contact you because I have a problem with the KOPY theme I have bought. Indeed since I did the update of WP and your theme the visual composer is not working anymore.

These are the problems :

• When I’m in the BO and wanna do some edit with visual composer, it’s loading but not showing my any of the blocks I’ve already set on all pages etc..
• When I want to add an element, I click on it and nothing happens

In other words I can’t do nothing with VISUAL composer in your theme.

Can you help me fixing this ASAP please ?

Thank you very much,

Regards
