mmmm, I didn't have any errors when I tried testing your site just now
try changing this part and let me know how it goes:
Code:
var threadid = $threadinfo[threadid];
document.write('<div class="news" style="line-height:12px;vertical-align:middle;"><div align="center" class="smallfont">');
document.write(' <strong>Aninda Oyla:</strong>');
document.write(' Vasat <input type="radio" name="rating" id="oneclick_vote_one_submit" value="1" onclick="javascript:void(0);" /> ');
document.write(' K?t? <input type="radio" name="rating" id="oneclick_vote_two_submit" value="2" onclick="javascript:void(0);" /> ');
document.write(' Fena degil <input type="radio" name="rating" id="oneclick_vote_three_submit" value="3" onclick="javascript:void(0);" /> ');
document.write(' G?zel <input type="radio" name="rating" id="oneclick_vote_four_submit" value="4" onclick="javascript:void(0);" /> ');
document.write(' Nefis <input type="radio" name="rating" id="oneclick_vote_five_submit" value="5" onclick="javascript:void(0);" /> ');
document.write('</div></div>');
be sure to load a page fresh by either clearing the cache or pressing CTRL+F5
Do you have any Firefox extensions installed? if so, which ones? (ones that would create issues would be NoScript or other JS specific ones)
