I am experiencing the same issue that several have written about.  A typical item page is found by clicking here:I am using a template override, but it I switch back to the default template for the category, they still don't show.  The social sharing code is there, and so are the links as shown by cursor behavior as you hover, but the icons themselves do not reveal themselves.  I also compared the two item.php files and they look the same.  In the override I moved the image gallery div below the item image view...otherwise unchanged.Anyone have any thoughts on this?Thanks Andrew

User firebug to hover over the area you are speaking of. See where it points.
The images are usually designated in a css file.
Could be k2.css or
if your using css4k2 could be in yourtemplate_style.css , a copy of k2 css.
You may have to move the images or change the css for it to find them correctly

Do you use onecsspercategory plugin?

The link seems to be broken however perhaps begin by setting all the "positions" in the social div in the item.php to "show" in the pages paremeters. Maybe they are being hidden because of it being inside a div which isnt being displayed because it is hidden using endif? The positions I refer to are for eg 

 

<?php if(  $this->item->params->get('itemHits') ||   $this->item->params->get('itemCategory') ||   $this->item->params->get('itemTags') ||   $this->item->params->get('itemShareLinks') ||   $this->item->params->get('itemAttachments')  ): ?>

 

other code

 

<?php endif; ?>

Then refresh to see if they display, if they do then set each to "hide" one by one to see where the probelm lies. Maybe the social icons code are wrapped inside a div which is hidden due to the parameter being set to "hide" so your icons are inadvertently being hidden too.. Another thing, are you using the default social icons or are you trying to insert a social sharing code such as "sharethis" into the html of item.php?

Could you perhaps post a working link so I can take a look? Sounds like a problem I had but must take a look to be sure.

Maybe you could post your item.php as an attachment too?

Anyone figure this out?? I'm having the exact same problem.
