error 500 JHtml icon not found in joomla 3.0: Game Magazine

I am using the game magazine template 3.0 for a site and whenever you click on the menu item to go to the article the error 500 JHtml icon not found error comes up.

In the back it is all linked but on the front the error keeps coming up. I am having trouble fixing the issue and unsure how to get it sorted.

Looks like something goes wrong during installation. When you switch to 'Beez' you don't have this kind of problem ?

Thats right - I switched to another template before and I didn't have this problem. So I guess if there isn't a solution I can use another template?

Thank you
