My website links do'nt work in IE8

Hi all,

I finished and uploaded my WordPress website yesterday and thought it was all working fine after testing with IE9/10.. Firefox and Chrome.

Unfortunately though, it appears under IE8 (all our work computers are IE8 Win XP) the site loads fine but none of the links work. Which ever link you click first loads, but then every subsequent link clicked reverts back to the first. Very occasionally it loads the correct page but adds it onto the bottom of the existing instead of refreshing.

Template: SMThemes Filmatic
Host: Godaddy WordPress package

I can’t seem to figure out the issue as the site loads and looks fine, its just the links that cause chaos.

Thanks in advance for any help, Mat
