The best way to find CSS selectors is to right-click on the element > inspect.

There are two ways to download Facebook reviews into the Plugin. 

1) If you want to use the Facebook API method then you would either need to be an Admin on his Facebook page or you could ask him to retrieve the access code and save it into the plugin...

2) You can use the Review Funnel method and all you need is the Facebook page URL. 

That is sort weight. You can use it to show certain reviews before others on a review template.

If the templates are on different pages then yes, put it on both. You can put it here...

Sorry, that shouldn't be in template 6 any longer. I'll take it out in the next update. In the meantime use this CSS to hide it. You can add this to the custom CSS for the review template.

span.wppro_viatext {
display: none;
}

Here you go. You need to use the Advanced slider and change the Time delay to 0.
