[TYPO3] New 404 page on multilingual sites

[Tomas Mrozek]

Thank you for pointing that out.
I actually tried the first proposed solution myself before posting my
question and didn't work for me.

Well, the corrected version does work so I'm posting it here again in
case someone runs into this issue too.

localconf.php:
---------------------------------------------------------------
if (preg_match('/^\/en\//', $_SERVER["REQUEST_URI"])) {
  $TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/en/404/';
}
else if (preg_match('/^\/de\//', $_SERVER["REQUEST_URI"])) {
  $TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/de/404/';
}
else {
  $TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/404/';
}
---------------------------------------------------------------
