vBulletin 4.2.1
I'm an administrator on our forum. I changed my password tonight (Settings > Edit Email & Password) and received confirmation that the change was accepted.
I tried to log in to the AdminCP with my new password, but it wasn't accepted. I verified three times that the password (new one) was being typed in correctly.
I changed my password back to what it was (Settings > Edit Email & Password) and tried the AdminCP again. Got in no problem.
My 'original' password is 15 characters long. The new password I created was 63 characters long.
Why would the AdminCP not recognize the 63 character password but the forum log in would?
I only wanted to increase the strength of my log in password for my account by making it more difficult to decrypt if my account were ever compromised.
