@Candace :
it seems the dynamic forms 3.30.50 is not working in safari was caused some clash with module on :
Gumbosoft PayPal Subscriptions Module v 3.0.1. these modules are installed together in the same page. disabling the gumbosoft paypal module will solved it, in my case we're goin to create 2 pages.
@khough : perhaps it's using another login name, Candace might be know
Thanks.
