Bug with my page

Good morning, I am writing to you because my site has been having problems with the Anspress plugin, and as you can see on my page when I click on the new topic or question button, all the fields in the plugin are tripled, I would like a quick and effective solution, Thank you very much for your prompt response. The page is http://54.159.133.50/questions/ask/ This is the test page so don’t worry about it.
