I am using multisite module to maintain three sites. In that i have used "hierarchical_select" module for a form.
In one of my multisite this form is working great, But in the same form for other site, I am getting following error.
I have attached a screen shot of the error.
As it is using the same files, i am thinking that it should be an configuration issues. But i have checked thrice for all the configuration and unsuccessful.
Please help.
Thanks in advance for any help
