so you get this error, even if you do not edit it?
if so, something is a bit strange, as its working for everyone else, on both etc and otc.
I can assure you there is no issue this mode on OTC, when downloaded ‘fresh’ from etc.io
if its still the same error… my first step if its still failing is to double check you have really replaced your edited copy with the version from the website, as most likely issue is somehow this has not been done correctly
fyi: the error your showing indicates that the ‘words’ array has not been initialised (hence why its is None)
obviously to help further Id need to see the code that you running
(this is why you have to be 100% sure you are running the right code, we dont want to waste time, trying to debug something thats not being run )
