Form changes not saved

Hi!

We have a problem in CRM forms . It does not allow us to save any form and we cant create new records. 

The CRM save buttons does not run and when you press it, a message is displayed "changes have not been saved"

When we run CRM inside CRM nodes it works OK, the problem is from outside.


Besides this, in the forms that contains custom scripts constantly displayed an error alert.

We believe it is a security issue in relation with httprequest but we cant resolve it.

Can anyone help us?

Thanks.
