[Rails Trouble]rails admin


Job Description

There is an error on rails admin. Does anyone solve this issue quickly?

[version info]
Rails 3.2.11
Ruby 1.9.3
Mac OS 10.7.5 and ubuntu 12.04

I am using rails_admin.
When I try to push one of the buttons/ drop down buttons, nothing happens. Instead, there is an error on safari.

[error message]
TypeError: Attempted to assign to readonly property.

// Make sure that the handler has a unique ID, used to find/remove it later
if ( !handler.guid ) {
handler.guid = jQuery.guid++;

[other info]
I don't use paperclip because when I try to launch Rails with it, it causes an error.

[how you work with me]
If your quick advice solves this issue, I will test it. I think if this is possible, it is the best.
If you need the whole source code and you deploy or you access to the server via SSH access and so on, it is ok too. But it may take some extra time.
