Not my scenario. It happens also if I close the browser. Anyway… if what you say it’s happening it should considered a serious bug. Who closes the browser before activating a just made account?
It’s also happening to my users.
I made some tests:
1) clicking on an email from thunderbird mail client gives me the error
2) clicking on an email from mailinator client gives me NO error
I’m going crazy. Many people has this problem but I can’t find a solution!
