I hope you have completed all the necessary criteria.
For example, minimum 700 words, at least two pictures, preferably owned by you, a video, a summary etc.
Is there any automatic warning as well?
Normally it takes few hours, which can be even 24 hours in some cases, after you hit the Publish button. Because the Hub is under QAP, that is quality assessment.
If everything is fine , it will be published. If not, you might get suggestions via email, by Team HubPages to make changes in your hub, before they publish it.
Wish you all the best!
