Not able to change save and summit to documents

sir, we are facing problem in erpnext and we are not able to save and summit the documents in Purchase Recepit,Purchase invoice,Sale Order,Delivery Note and Sales Invoice.

There is no issue in standard workflow unless you made custom workflow.

Only reload browser may help.

i will try it but no any result of document.

Describe more over it. Version ? Branch ? OS ? Memory ? has any customization ?

There is lots of dependencies works behind ERPNext…
