Problem with "Ask a question" pop up on touch devices

I have a problem with "Ask a question" pop up on touch devices. 
When i click on it, a pop up is shown (not centered in my screen) that has no content and the website is non responsive. The pop up remains and i cannot make it disappear.
There are some cases that the pop up is not shown and instead of that, it loads on the same window.
This happens in the InStyle demo page too and i have tested it in iOS and Android.

Any help?

Could you check whether the same happen on default Joomla! template like Beez ? I suspect that it will be the same because this is VirtueMart issue and you should contact with VM support.

I changed the template of the website to Beez and it works fine. So I can’t think of what’s the problem. 
I change the theme back to InStyle and the problem is there again.

Any help…?

Could you give me your site URL ? It is always easier to check CSS/HTML code on live site.

Happens also on the link of your demo site:
http://demo.gavick.com/joomla25/instyle/index.php/virtuemart/product-details-layout
Open the website from an iphone/ipad device and go to "ask a question about the product"
The popup doesn't have a close button (x) and is empty.
Not responsive ready.

Any news?

This is default VirtueMart behaviour and not part of our template. The facebox script is computing the position of pop-up in wrong way but for me the same happen on default template also. Please try to add this code to tablet.css file :

Code: Select all

#facebox { left: 50px !Important}

and check whether this resolve this issue.
