Blank page after putting article in basket

-- url of the page with the problem -- : www.yohocards.nl
-- HikaShop version -- : 2.2.3.
-- Joomla version -- : 3.2.1
-- PHP version -- : 5.3.10
-- Browser(s) name and version -- : firefox 26.0
-- Error-message(debug-mod must be tuned on) -- : Error_message

It worked first fine but now I get a blank page after I want to put an article in the shoppingbasket. The popup message does not appear anymore. On the shoppinglist there is no button to place to order. Alle settings are fine as far as I can see.

Problem solved, apparently a menu item for the shoopingbasket does not work, activating the module shopping basket does.

Thanks for your feedback .

But now I have to click twice on the shoopinbasket link before it is shown, after clicking once I get a blank page. Is that a caching problem?

I just checked your website and it seems like you have some JavaScript errors through your website, so I think that reading this thread will probably help you.

I have instaaled the jquery easy plugin but that does solve the problem. At the beginning the popup was working so it cannot be a big issue. The popup windown for the general conditions is working fine so mootools does the job. But still no popup window when adding an article to the shoppingbasket en still a blanc page when clicking on the button 'go to shoppingbasket'.

I reinstalled the contentmodule and now the popup window appears again when adding an article in the shopping basket. However the links in the popup window don't work, neither go on shopping nor go to shoppingbasket. They both give a blanc page
