XF 2.1 Server log error how to debug

[John_Jiang]

Hi, i'm a newbie. just have a forum setup. the log has this error: Invalid parameter
Zend\Feed\Writer\Exception\InvalidArgumentException: Invalid parameter: "name" must be a non-empty string
src/vendor/zendframework/zend-feed/src/Writer/AbstractFeed.php:253

looks like some function called with empty argument. I havn't done much customization or change of default values post installation. how to fix this particular problem. and in general how to best find and fix errors in the log? thanks a lot.
