Problem to the store page

[creositi]

Hello, I have a problem with virtuemart.
I use:
joomla 2.5.19 Stable
virtuemart 2.6.0
php 5.3.28
When I go into Virtuemart and after shop (and only on this page) everything freezes, the page continues to load but without giving errors. If I move the mouse up and down the page does not go up and not down, and if at that time I go to the site frontend, it displays a blank page.
But as I said it only happens if I go into Virtuemart and then shop. Can I use anything else, I put categories and products without any problems. I can also add new payment methods and shipping, but I can not edit the information in the store.
Oh, one important thing is that it not has given this problem right away. The first few times I was able to change the data store. Then it started to not work anymore.
Until this problem I had installed the component widgetkit, but if I uninstall this component the problem is not solved.
Can you help me?

Not a good solution but you can try to use other web browser.
