Answer 1

You can check what exception occurred in your Magento system by navigating through:

• [Document_Root]/var/report folder and
• Open the file # corresponding to exception number on your browser's screen.

or

you can enable exception printing for debugging purposes by:

• Open [Document_Root]/errors folder
• Rename local.xml.sample to local.xml

Both ways are helpful to trace and debug exceptions and errors in Magento.
