[TYPO3-UG Dutch] Real URL gaat af en toe onderuit

[Rens Admiraal]

Lo allen,

Ik heb een vreemd probleem met real url. Ik heb een pagepath  
ingesteld zodat de paginatitels de url bepalen. Nou is het echter zo  
dat om de zoveel tijd (wisselt) de url's opeens omgezet worden naar  
de page id's. Resultaat is de foutmelding '20 is not a postVarSet as  
expected'

Na het clearen van de cache is dit opgelost, weet iemand hier de  
reden van?

Hieronder de configuratie:

$TYPO3_CONF_VARS['EXTCONF']['realurl'] = array(
	'www.domein.nl' => array(
		'init' => array(
			'adminJumpToBackend' => 1,
			'enableCHashCache' => 1,
			'enableUrlDecodeCache' => 1,
             'enableUrlEncodeCache' => 1,
		),
         'redirects' => array(),		
         'preVars' => array(
    			array(
				'GETvar' => 'no_cache',
				'noMatch' => 'bypass',
			),
         ),
		'pagePath' => array(
			'type' => 'user',
			'userFunc' => 'EXT:realurl/ 
class.tx_realurl_advanced.php:&tx_realurl_advanced->main',

			'expireDays' => 7,
			'rootpage_id' => 57,
			'firstHitPathCache' => 1,
			// 'encodeTitle_userProc'=>'EXT:realurl/ 
tx_realurl_encodeTitle_userProc.php:&user_encodeDates',
		),
		'postVarSets' => array(
			'_DEFAULT' => array(
				
					// news archive parameters
				'archief' => array(
					array(
						'GETvar' => 'tx_ttnews[year]',

					array(
						'GETvar' => 'tx_ttnews[month]',

							),
						),
					),
					array(

				),				
			),
		),
		'fixedPostVars' => array(),
		'fileName' => array(

	),
);
