Outdated Paypal

When purchasing rp, I get brought to an old version of paypal where I have to log in, and after logging in I get sent into the newer version of paypal to log in again, and when I do login I get an error saying, "You have requested an outdated version of PayPal. This error often results from the use of bookmarks." Im not sure how to fix this problem but sadly I probably wont be able to get that skin I wanted and have been waiting for ages to get. ty riot
