Please, answer me, at least this time
There are so many reasons for this; You could have set some options wrong, you could be using the original Qu'an bot and not your personalized version, you could be trying to publish a poll inline while not having set your bot inline, etc. etc.
I can't help you to solve the problem, I am a mere user of the bot myself - and not a very expert one - but I can tell you that if you want to receive an answer it would help if you specify all the details of your problem: what are you doing exactly, where, what is your purpose, what happens instead, what is the error message you encounter if any, etc. etc.
Simply saying "I can't publish a poll" is not going to attract many answers I am afraid.. :)
