Subject Re: [ASF-ICFOSS MENTORING COMDEV-92] Regarding Live Syntax Highlighting
Date Wed, 18 Sep 2013 07:40:28 GMT
Hi Ryan,

I have been trying to make the plugin for a couple of hours before but seem
to have come across this error:

TypeError: pre_process_request() takes exactly 2 arguments (3 given)

But I have used only 2 arguments in the code i.e as follows
def pre_process_request(req, handler):
        return req, handler

Could you please help me with this?

Thanks & Regards,
