Unable to add share button

St Laurie

I am unable to, for some reason, add a share button. It adds to the specific block I drag it to however the icon does not appear. I went through my site wide CSS blocks and cannot see anything pertaining to the share button. When I click the spanner to configure the share button I get this:

and I cannot click cancel or done to get rid of it, I need to refresh the page.
Anyone else seen this?

So turns out it was Chrome blocking the content. Might have been ghosty or adblock plus. Opening in IE or disabling extensions worked.
