Hi!
I was browsing forum for PayPal problems and found a few useful posts, but no one had issues with return url like I have.
I'm using nop 1.9. As I try to activate raturn url on PayPal admin it keep saying that url can not be validated, even though that the site works all the time and the requested file is right there.
Anyone had similar problem? Any thoughts, solutions, ideas?
Thanks!
