Repeated item showing up in my logs. Unclear what this is / what I should do. The URL of the page that the error occured on does change at the &url=xyz

Is this something you're actively seeing still? It may just be a user messing with the redirect URL which then would be correct that it's erroring out if that doesn't exist.

Appears to have stopped and the "repeated log message" warning under support tab is gone. Thanks!

Glad to hear that it resolved 🙂
