i found it impossible for us to use k2 in china,especially about twitter and facebook,please teach me how to solive it,may be i should disable the share button?

Hi. Regarding the placeholder images, the Gravatar service is used. So your site must be on a server not on localhost. Regarding the Twitter and Facebook since they are blocked you cannot do anything. You need to remove the share buttons. Please read getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates . Then create a template override for item.php and remove the code from there.

thanks a lot！i have removed the share button,then i found it can't input anything on it ,would you please have a look?my website is master.xinkejituan.com/index.php/zh/collection-appreciate
