I went to the Your Characters page from the menu on the left. I clicked on Delete for a character I no longer needed and got the expected pop-up confirmation; I answered yes. I was then redirected to this URL:
https://everquest.allakhazam.com/cgi-bin/Apache=SCALAR(0x961c09c)
Clicking the Back button took me to the character listing again, with the character still listed. I tried to delete the same character again and got the same redirect. I then clicked on the character's name to view it and was told the character does not exist. Refreshing the Your Characters page showed that the name was removed.
Any ideas?
