Traceback
A Python "traceback" is a detailed error message generated when an error occurs in executing Python code. Since Plone, running atop Zope, is a Python application, most Plone errors will generate a Python traceback. If you are filing an issue report regarding a Plone or Plone-product error, you should try to include a traceback log entry with the report. To find the traceback, check your event.log log file. Alternatively, use the ZMI to check the error_log object in your Plone folder. A traceback will be included with nearly all error entries. A traceback will look something like this: "Traceback (innermost last): ... AttributeError: adapters" They can be very long. The most useful information is generally at the end.
