safari and ERP programmes

hi

i have a serious problem about entering our ERP programme by safari. I can reach to password screen but after entering username and password, i can not able to acces to the ERP programme...

i get in touch with the company of the ERP programme but they are not sure about the issue... i can open it on safari pc version but not on my mac, so i better choose to ask to you professionals 🙂

thanks

levent.
