Troubleshooting

 * This script may not work if you are using memcached on your MediaWiki installation. You can restart memcached to make it clear its cache and allow you to login again.
 * Windows has special challenges with parsing double-quoted strings, as when a username or password contains spaces in the second example above. You may find some illumination on this issue here (autohotkey.net)&mdash;or it might just make your brain hurt.
 * Occasionally triple ("""quoted string""") and quadruple sets of double quotes will solve your problems with Windows' command shell, cmd.exe. You may be happier, though, to try Cygwin and follow the Unix conventions for quoting strings, which are a bit more sane.
