Fatal Error

Hi,

I keep having trouble updating my theme. I’ve finally got to install but now the required plug ins for the theme don’t work.

I’m trying to activate Visual Composer and i’m getting this error

Fatal error: Cannot declare class Vc_Manager, because the name is already in use in /homepages/23/d607642202/htdocs/clickandbuilds/VotingCounts/wp-content/plugins/upside/js_composer.php on line 33

This is the first time i’ve used wordpress. Please can someone tell me how to fix this because without this plugin the website doesn’t work. and i’m hoping to launch tomorrow!

Thank you!
