after upgrade vm from 3.0.11 - 12 i am experience problems when i click on the next or previous product in the product page
The screen stays diffuse - white, and i cannot click on anything anymore... page does not come out of the "loading state"
When i analyse the page i see in the body : "vmloading"

how can this be solved ?

Your site is generating JavaScript errors. Disable JCH Optimize plugin and check again.

I also see some invalid JavaScript in your site like below:

Code Select Expand

$(window).scroll(function() {
if ($(this).scrollTop() > 3){ 
$('').addClass("");
}

});

You need to remove it from your site.

Please update to vm3.0.12, but this error is hard to avoid. Sql ordering stuff, not easy to explain. I tried to enhance it, but it is hard to make it perfect without too much perforamance problems.

@ Jumbo : Thanks for the advice, I've disabled parts of the JCH optimize. and it seems to work

Where can I find this code ?

@ Milbo : the problem started when i switched to 3.0.12, before that everything was fine.

Where can I find this code ?

Your template developer should be able to help you on this. I can never know where they added the codes.
