Do me a favor and take a screencap of the issue and post it in here. I would like to take a look, since I cannot see it myself.

Any issue would be related to the Button itself and not the theme, but perhaps I can help out...

Thanks,
Justin

Found this tip if that's got anything to do with it. Sorry, I'm pretty hopeless on the code side of things.

The demo is not showing it for me either. Just a blank white button with no link. Tested on latest Safari and Chrome.

Same prob on Themeforest site theme pages like yours http://themeforest.net/item/the-navigator-premium-wp-location-guide-blog/397351 with the button blank on the right.

Another weird one. Haven't messed with code there. Was working previously. Any other with the same problem out there??

I see the Facebook button just fine, see here: http://molitor.justinhandler.com/wp-content/uploads/2012/04/facebook.png

What browser are you using? (shouldn't matter)

And can you send me other example sites that don't work?

Does the demo work for you? http://themeforest.net/item/the-navigator-premium-wp-location-guide-blog/full_screen_preview/397351

Yeah, a plugin was the culprit.

Plugin name was User Access Manager. Tried to toggle all kinds of settings but the theme just didn't seem to leant to display thumbs.

Found an alternative plugin: Wordpress Access Control.
So, anybody reading this who needs a plugin that controls user access to specific pages and posts, this one will work.
Thanks for your time Justin.

P.S. The Facebook graphic in the Shared drop down is now blanked out. I've also seen it on other sites and tried to find the replacement URL for the graphic but no luck. Any tips on this?

Yeah, you're going to want to try and deactivate them 1 by 1 until you identify the problematic Plugin.

Let us know!

Thanks,
Justin

Hi and thanks for the tips.
Still no joy. Reverted back to original code and that didn't do the trick. Also have featured images on every post.

Can only guess its maybe plugin related?

Hopefully this helps - thanks Translymaniac.

Hi,
don't know if this helps, but I had the same issue with some of my posts. Turns out I did not assign any featured image to the respective post, hence they would show up blank in the related section.

Hey there,

I would assume that when you changed the Related Items within the code it messed things up. Please change it back to the original title and let me know if they appear again.

Thanks,
Justin

Thanks for the great theme. It's a pleasure to work with.

I am having problems getting the small thumbs to show in the Related Items section of the post page.
I've added tags and they seem to be there but the thumbs are blank and also no tooltips.
An example of one my posts is here: http://www.shoppeek360-perth.com.au/child-education-services/

The thumbs and tooltip worked initially and haven't changed any code besides the Related Items title. They seemed to not show possibly after I updated Wordpress.
Any help would be greatly appreciated.
