I cannot access my control panel.
If I set the config file to use either “c” or “cs” for admin logins, the login page reloads without letting me in. If I change it to “s,” I get the “Disallowed Key Characters” error.
I updated that error to show the string that it is crashing on, and it’s crashing on the login name, which is 7 characters, all lowercase letters.
Clearing browser cache/cookies doesn’t help.
2.1.3 installed. Disabling extensions doesn’t help.
The error occurs in both IE8 and FF3.6. It is local to this site; I can log in to other EE sites just fine.
