The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

well, you are using python 2.6, which does not support "{}".format syntax, please upgrade your python version at least to 2.7 or 3.x.

BTW, please delete the data.db3 if you was already failed to start the web, it might be in broken state already. The application will recreate one if it does not exist.
