TYPO3: added new language and get 404 page not found - multilingual

Question

I added a new website language to a TYPO3 project. The new website language has id=2. But if I call e.g. www.your-domain.com/hr.html I get 404 - page not found (normally the start page in the translated language should appear). Also the menus show the links without /hr/. I can call the pages with http://www.your-domain.com/index.php?L=2. The configuration for Typo3 looks like
config {
linkVars = L
sys_language_mode = content_fallback
sys_language_overlay = hideNonTranslated
sys_language_uid = 0
language = de
locale_all = de_DE
htmlTag_langKey = de-DE
}
[globalVar = GP:L=1]
config {
sys_language_uid = 1
language = en
local_all = en_GB
htmlTag_langKey = en-GB
}
[global]
[globalVar = GP:L=2]
config {
sys_language_uid = 2
language = hr
local_all = hr_HR
htmlTag_langKey = hr-HR
}
[global]
The RealURL configuration is
'preVars' => array (
'0' => array (
'GETvar' => 'no_cache',
'valueMap' => array (
'nc' => '1',
),
'noMatch' => 'bypass'
),
'1' => array (
'GETvar' => 'L',
'valueMap' => array (
'de' => '0',
'en' => '1',
'hr' => '2',
),
'valueDefault' => 'de',
'noMatch' => 'bypass',
),
'2' => array (
'GETvar' => 'lang',
'valueMap' => array (
'de' => '0',
'en' => '1',
'hr' => '2',
),
'valueDefault' => 'de',
'noMatch' => 'bypass',
),
For me it looks like that everything should work, but it isn't. I also cleared the RealURL Cache with
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['clearAllCache_additionalTables']['tx_realurl_urldecodecache'] = 'tx_realurl_urldecodecache';
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['clearAllCache_additionalTables']['tx_realurl_urlencodecache'] = 'tx_realurl_urlencodecache';
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['clearAllCache_additionalTables']['tx_realurl_pathcache'] = 'tx_realurl_pathcache';
in the localconf.php and pressing the Clear all caches button. I'm using realurl 1.12.1 and Typo3 4.5.5. I also looked into the htaccess and didn't found anything special. What I'm missing?

Answer 1

On the page urltool was removed but the include of urltoolconf_realurl.php was still there (with the old settings). This include in the localconf.php has overwritten my settings of realurl_conf.php (which included the new language).
But still some menus have index.php?id=69&L=2 in the URL instead of the speaking URL. So they were links to other pages and I had to set the links again and make sure there was a translation available (even in folders ...).
