XF 1.5 Error: Request not validated (User upgrade TX log)


Well-known member
Hi folks,

I'm testing my new XF install and while testing the user upgrade process - which worked ok - I saw this in the transaction log.


Is this a problem?

My test user did get upgraded and all seems to be well with it.

It could have reflected a temporary issue in PayPal, as that message indicates that PayPal couldn't confirm the request as legitimate. Given that the next 2 messages are normal (and they all happened within a minute), I think it can be disregarded, but it's worth keeping an eye on.
