Two popup window open

[chewic]

Hi. When I clicked the facebook or the other link buttons, two popup windows open. I have added this: googleplus: { shareUrl: 'https://plus.google.com/share?', params: { url: this.getValue('url'), } },

And the googleplus button works perfect. One window. But the other links(no whatsapp or telegram) open two same windows. What is wrong? Thanks.
