Visual composer disable in Fortuna theme

Hi,

Visual composer comes with Fortuna. But since I installed the theme, the Visual portion of the tool is not available.

I wrote to Visual Composer support and they advise me that the tool was deactivated by the theme:

“The front-end editor at your end is disabled by the theme author using vc_disable_frontend function. You can get in touch with him and get rid of the above code from the theme to get it back.”

Please advice.
