Got a pretty strange issue here, maybe someone had similar experience. When loading http://magento.dev/index.php/cmd/sales_order_status/ locally it crashes with message
Cannot retrieve entity config: sales/order_status_label
though on the same database (which is imported to the local server, I’m using MAMP Pro 2.0.1) but on the live store it works perfectly and opens the page
Could it be because of database or PHP differences? MySQL 5.5.9, PHP 5.2.17 on the local versus MySQL 5.1.56 PHP 5.3.6 on the live
I can attach a stack trace if needed
Issue was due borked config.xml in core Sales module.
Generally such error means that the node in section is missing or wrong for specified model and
getEntitymethod inMage_Core_Model_Resourcereturns an empty string
