When I add a new service, the live preview visually cuts the icon of the new service.
The service I added is from vk.com ( A russian version of facebook) and the ‘B’ icon form vk.com gets visually cut and I just see a blue line of the icon between other 2 icons.
I chose the icon only option here.
Having said that it displays correctly on the website. so it is purely a live preview issue i think.
Not sure if I really need it work in the back end but I thought it might be good to inform you folks about this anyway.
