Issue with Twitter share

Hi, i have a problem when sharing on twitter it opens 2 popups eg here http://socialmediaxplosion.com/5-things-you-should-be-doing-with-your-social-media/
If this is indeed a theme problem (as you mentioned on another support thread here) does this mean that the only solution would be to use another theme or find another plugin? Or is there another solution?

(Sorry for also posting on that other resolved thread i just wasn’t sure if i should make a new thread or not)
