error - "This page has changed since you started your edit."
I am getting the following error and am struggling to find a fix.
"This page has changed since you started your edit. Refresh your page and try again."
The code has been running fine on developer accounts on na6 and na7 but is now failing on cs2! Turning on logging doesnt pick up anything. I don't understand why it works fine on one instance but not the other... dont think there is anything in the config that is much different. Refreshing does not help.
I think the error may happen during a redirect but I will have to go through the code - just wondering if anyone has seen this one before?
