looking at it.
throws a javascript error, but right now not sure where its coming from
(says something like

Uncaught TypeError: object is not a function
somewhere here it seems

(function(term
/**/) {
return wppizzaCartCommentToggle(term);
})

not sure why (did you add/edit any js anywhere ?
could you also – at least once now – clear the cache on that page ?

ok, your issue seems to be here:

something somewhere inserts this (i’ll have a look in a minute why that may be , but just posting this first):

<script>
var getElementsByClassName=function(a,b,c){if(document.getElementsByClassName){getElementsByClassName=function(a,b,c){c=c||document;var d=c.getElementsByClassName(a),e=b?new RegExp("\\b"+b+"\\b","i"):null,f=[],g;for(var h=0,i=d.length;h<i;h+=1){g=d[h];if(!e||e.test(g.nodeName)){f.push(g)}}return f}}else if(document.evaluate){getElementsByClassName=function(a,b,c){b=b||"*";c=c||document;var d=a.split(" "),e="",f="http://www.w3.org/1999/xhtml",g=document.documentElement.namespaceURI===f?f:null,h=[],i,j;for(var k=0,l=d.length;k<l;k+=1){e+="[contains(concat(' ', @class, ' '), ' "+d[k]+" ')]"}try{i=document.evaluate(".//"+b+e,c,g,0,null)}catch(m){i=document.evaluate(".//"+b+e,c,null,0,null)}while(j=i.iterateNext()){h.push(j)}return h}}else{getElementsByClassName=function(a,b,c){b=b||"*";c=c||document;var d=a.split(" "),e=[],f=b==="*"&&c.all?c.all:c.getElementsByTagName(b),g,h=[],i;for(var j=0,k=d.length;j<k;j+=1){e.push(new RegExp("(^|\\s)"+d[j]+"(\\s|$)"))}for(var l=0,m=f.length;l<m;l+=1){g=f[l];i=false;for(var n=0,o=e.length;n<o;n+=1){i=e[n].test(g.className);if(!i){break}}if(i){h.push(g)}}return h}}return getElementsByClassName(a,b,c)},
dropdowns = getElementsByClassName( 'dropdown-menu' );
for ( i=0; i<dropdowns.length; i++ )
dropdowns[i].onchange = function(){ if ( this.value != '' ) window.location.href = this.value; }
</script>

if i take this out , it works just fine…..

> Did you just remove an insert

i didnt do anything (other than trying to figure out what the deal is)
i assume it was a caching issue (my best guess here)
