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.

Hey Gerd,
It would be best to start over. Just go to the Review List and delete all reviews. Then delete the Review Funnel. Then just use the Google Crawl to download the reviews. In the Badge you should be able to use source site.
Hey Gerd,
One review = to one credit. However it also costs 10 credits to run a scrape job. So if you download 15 reviews it will cost 15 credits + 10 for the scrape for a total of 25 credits.
To fix the total mismatch I would go to the review list and delete all the reviews and then re-download.
Which Google download method are you using and what are the search terms or place id?
I agree the icons should be svg. I just haven't had time to convert them or find new ones.
I've added a filter in the next update. If you want to go ahead and add it to your version here are the steps.
Edit this file...
WP-Review-Slider-Pro\wp-review-slider-pro\public\partials\template_class.php
around line 761 before the return add this line...
$logo = apply_filters( 'wprevpro_modify_sourcelogo', $logo, $review, $currentform );

Then in your theme functions.php file you can use it like so...
add_filter( 'wprevpro_modify_sourcelogo' , 'modify_sourcelogo', 10, 4 );
function modify_sourcelogo($logo, $review, $currentform) {
if($review->type=="Google" ){
$newlogo = '
';
}
return $newlogo;
}
