This question already has an answer here:
I m new to magento and php. while I m learning, try to write some code but unable to find where the error is. for example I m trying to build the grid in admin panel. I have followed the instructions from different tutorials. But could not find where the error is. there is no line or clue in exception log or system log. So how to find where the error is or Actually what happening so that I could not see my output. I m using php storm IDE. On creating Admin panel grid I could not load adminhtml/mymodule.php, what would be the issue?
