I tried running a script on wmru:, but whenever it reaches the saving method, it spits out the error: "NoUsername: No username has been defined in your user-config.py: you have to add in this file the following line: usernames['wikimediachapter']['ru'] = '1234qwer1234qwer4'". I've created user-config.py then, which has not been needed on testwiki, commonswiki, and wikidatawiki (the projects at which I used PAWS before), but the issue persists. What am I doing wrong?
