I have a problem that icons like facebook logo doesn't show up properly.
I have been reading about this here

http://forum.bytesforall.com/showthread.php?t=21116
And I copy paste code to my various.php (see the photos).
It doesn't work.
Could you help me with that, please?

My web page : www.projektowaniebim.pl

didn't you want to put 'http' at the start of your URL for the background-image in the CSS?

Where should I enter my URL ? Here (photo) ?

Hmm, according to Andy from Shareaholic, they fixed their CSS, but I guess they either didn't test something carefully or left something out.

Try adding this to the end of your various.css file:

ul.shareaholic-share-buttons li.shareaholic-share-button i.shareaholic-service-icon {
   background-image : url("//dsms0mj1bbhn4.cloudfront.net/assets/pub/share-buttons/2014_04_01/classic-popular.png");
}

Yes, it worked ! Thank you !
