We are experiencing an issue where the "web version URL" and "forward to a friend" links in our test emails will work fine, then after another send get an error message. Has anyone experienced this and have you found out why it happens?
Yes, all other links are working fine. I find it odd that they will work one time, then not another. I just want to make sure it doesn't happen in a live send. It hasn't yet, thank goodness.
