Please watch down the facebook widget. There is an empty widget box corresponding to the chat FlexyTalk Free Live Chat Widget. It takes a space but does not show the title or anything, just a white box.
I see. Some themes display the space although it’s not specified in the plugin source code. If you choose the “Flow” option on the widget positions settings, the chat button should be displayed in that widget area.
Unfotunately there’s no easy way. You would need to edit the source code of the plugin. In a near future we will include shortcodes to customize the html output of the chat button when the default behavior does not meet your needs.
