The new versions of Magento do not show the error report on browser. Instead they are stored on separate files and the file name is shown on browser. This is a great feature which is done for safety.
However while developing it becomes a little irritating to open the error files every time. So, if you want to print the error reports on browser during development do the following –
1. Open the file errors\local.xml
If you do not get a file with the same name, look for local.xml.sample and rename it to local.xml
2. Look for the
print will show the error on browser and email will mail it.
