I recently posted about some failure in changing my email address on various big-name websites. One of those, was Blizzard's Battle.net system, used to login to Blizzard games such as World Of Warcraft. The problem was that an error was occuring, but the error text was not displayed:

This problem has now been fixed, so today I was able to see what the actual error was:

"Your password cannot by the same as your email address"

Now, I know what you're thinking. What am I doing having my email address as my password? Well, I don't. However, if you ignore case, the first few characters were the same. Looks like this was the problem all along.

Now I knew what the problem was, it was easy enough to change my password, and then I could successfully change my email address.

+1 to Blizzard for fixing the error message not displaying, but -1 for not making it very clear. I thought the validation was working against the wrong input boxes for a minute. Better wording would be that "your password cannot contain part of your email address" or similar.

I'm just happy I managed to fix it before having to share the old, defunct address for Real ID :-)
