[TYPO3-english] After upgrading from version 4.4 to 4.5 stopped working "shop_manager"

[Fred Moroz]

I have 2 warnings
PHP Warning
PHP Warning: ksort() expects parameter 1 to be array, null given in 
/home/seoru/bolarm.seo.ru/docs/typo3conf/ext/shop_manager/mod1/index.php line 486
PHP Warning: Invalid argument supplied for foreach() in /home/seoru/bolarm.seo.ru/docs/typo3conf/ext/shop_manager/mod1/index.php line 488
Errors due to empty $list_orders
But he was not empty in version 4.4, how can I trace the problem?
