I figured out what happened. I had opened a new tab in FF and logged into the admin UI and from there viewed emal as another user. That aparently breaks something in the first tab. What is strange is in the original tab where I was logged in to begin with I have been able to send and receive email all afternoon but when I tried to view headers or an attachment it gave me the error. I logged out and back in and all is well. I will have to remember that. |
