Hello,
I have just tried upgrading from 4.1.12 to 4.2 on a test environment, and gets the following error when viewing a post: "A required field called ip is missing or has an invalid value."
It is only in showthread.php this error occurs.
I have tried with a CLEAN install of 4.1.12 and then upgrading to 4.2. NO plugins whatsoever, just a plain, clean install.
Find this really odd, as I've never experienced problems upgrading before (this is a forum that has been running since vB 3).
Anyone else having this problem?
