[TYPO3-english] Cronjob for scheduler: localconf.php is not found!

[Stefano Kowalke]

Hey folks,

I configured the schedule cron job. The path for the job is
/home/www/web431/html/cms/typo3/cli_dispatch.phpsh scheduler.

Unfortunable the cron exits with an error:
PHP Fatal error:  Uncaught exception 'Exception' with message
'localconf.php is not found!' in
/home/www/web431/html/typo3_src-4.5.3/t3lib/config_default.php:670
Stack trace:

/home/www/web431/html/typo3_src-4.5.3/t3lib/config_default.php on line 670
X-Powered-By: PHP/5.2.9
Content-type: text/html

The code in config_default.php at line 670 is:

	// Include localconf.php. Use this file to configure TYPO3 for your
needs and database
if (!@is_file(PATH_typo3conf . 'localconf.php')) {
	throw new Exception('localconf.php is not found!');
}

in normal mode the constant "PATH_typo3conf" is correct (i checked this
with "var_dump(PATH_typo3conf);"), but it seems that in for CLI script
it is wrong and localconf.php was not found. I can't check this because
I don't have a ssh account.

According to the hoster, safemode is off.

Can anybody give me a hint in which direction I have to search.

Thanks in advance
Stefano
