Paypal Login Pop Up Opens And Closes Itself

[rizone]

Hi

I am very new to Prestashop and this forum.

I have recently setup the website and still trying to get around and know prestashop in some details.

 

While setting up paypal module to use it as login for customers, i have made an app on paypal but was having trouble with redirect url on paypal, which i managed to solve after going through this forum.

 

However now after sorting that issue now when i try to login with paypal at checkout, a pop up paypal window opens and closes itself without me having to enter any details.

 

Has anybody came across this issue before. Please help.

Thank you
