Template error in IE7, IE8.

When I load my site with the template The World News on the Internet Explorer 7 and Internet Explorer 8 is a warning error (image attached). Using firefox with firebug I get this error:

syntax error: "image_generation" (line 965)

$ G is undefined: var fx = new Fx.Slide (the, {duration ...], transition: $ G ['animation_type']});, engine.js (line 66)


Gk_news module is apparently because when I see an article the error not only on the main page, I wanted to know if there was any update for gk_news or you could give me some solution.

Joomla Version: 1.5.23
GK News: GK1 v.1.0.0
