My errors/local.xml content:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<skin>default</skin>

</config>
Is it possible to display warning in browser?
PS:
I can see errors in browser when they are.
But I would like to see warnings also, not just in log file.
Enable developer mode. In Magento > 1.3 you need only set an environment variable (MAGE_IS_DEVELOPER_MODE) as this is evaluated in index.php.
