by the way , you can probably just ignore what i said about that script above
probably was just an overlap in between you clearing the cache and me taking out that script and it suddenly working

nothing wrong with caching things (in fact i’m all for it) but you should really clear any caches after plugin updates (in fact the caching plugin should actually alert you to that fact)

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…..

also , which version did you update from btw ? (if you remember)

good stuff

feel free to post a review though 🙂
i could do with some more (positive ones of course)

>Thanks a lot, and I will have a try.

by all means of course, but if you give me a couple more days (just testing an additional option to make sure nothing else breaks) i’ll release an update and show you how you could set this up with your original requirements

>Besides, will you implement the sorting function on showing menu items of a category?

no, because that’s not a plugin issue/function/option but down to wordpress

> I found it needs to change the time one by one to make it in sequence.

whats wrong with using the order attribute ? (you can even get there from quickedit)

> And Could you tell me which file and statemnet I can directly modify to make it sorting by item name in ASC or DESC?

as i mentioned, that’s down to wordpress, but – in any case – there are plugins that let you also do a simple drag and drop
this one does a fine job in my experience:https://wordpress.org/plugins/intuitive-custom-post-order/

v1.1.1 addresses this now by loading that text dynamically via ajax if using a cache plugin instead of inserting it onto the page
(note: “i am using a cache plugin” has to be checked in wppizza->settings)

simple issue is , that the pages are cached (i.e you “recently” turned on a caching plugin)
the current preorder plugin doesn’t deal with that , but i’ll do something in an update that should address that too

will take a few days, so in the meantime taking that text out as you did is probably a good idea (or you could disable your cache plugin of course as a temporary measure)

must admit, that looks a bit strange
i’ll have a bit of a more indepth look tomorrow if you dont mind (its late here)

one thing that puzzles me though: what exactly do you mean by “recently” ? what changed ? did it work fine before ?
