Hi, I tried to make a paypal purchase, redirected me to the paypal page and once I entered the data I could not continue. Thank you

This sounds like a PayPal problem to me, since the page you get redirected to is theirs.

You can try with Plarium's support, but I have a feeling you'll need to contact PayPal's one.

Before doing either, I suggest you try again. Maybe it was just a temporary glitch.
