Issue with category price on IE 8

-- Browser(s) name and version -- : I.E.7-8

Hi,
today a customer report me an issue.
I tryed and i saw the issue.
I have some products with categories and every category has its price.
If you use I.Explorer 7 and 8 you can see that when you choose the category the price does not change.
With the latest version of IE there is any bug.

Hi,

The issue comes from the fact that the javascript code of the header is compressed by something on your website and old versions of IE have a hard try reading it, creating a javascript error preventing the characteristic system to work properly.

Hi,
yes, i use JCH Optimize Plugin to improve my site.
But i have already excluded Hikashop cause other issues.
Do you think there is a solution?
Or, do you think there is another plugin that work better to compress Hikashop?

Hi,

You have excluded HikaShop, but not the javascript of HikaShop which is in the header of the page.
Deactivate JCH Optimize and see if that works.
Compressing the javascript on the header of the pages doesn't change much to your page speed. Try to turn just that off in the options of the plugin (if such option exists).

I,
i tryed each option and i find that was "Minify HTML" option to do the issue.
Thank You!
