[antonino78]

Hello,
shipping address on the page is not working dropdown menu state / province
Could you please help me?

[antonino78]

My version virtuemart 2.0.26d
The problem only occurs on the page to add your shipping address.
On the registration page it works correctly.
Please give me a help?

Usually a JavaScript conflict.  url?

[antonino78]

How can I check if there is conflict?
I also changed the template but the problem remains

If it still happens with the beez20 temp[late then it is likely to be caused by a third party plugin such as  Simple Image Gallery Pro.

Use a debugger to check js issues - http://forum.virtuemart.net/index.php?topic=119638.0
