Not able to ask question on my site

I had installed AnsPress long time ago on my site. Today when I tried to ask a question, the question is not getting published. When I click on Post question, it show loading icon in the middle and then vanishes and nothing happens after that. I am not getting any error about why the question is not getting published.

I uninstalled it and again installed today, but I am getting the same problem.

Please help!
