All is working fine, visit here (and it will work with other plugin too): http://www.pigomultimedia.com/testing_area/beta_site_9ZH/anspress-q-a/ask but link of ask button is: http://www.pigomultimedia.com/testing_area/beta_site_9ZH/press-q-a/ask which is wrong. I dont know why its happening. But AnsPress ask page is fine, just link in ask button is wrong. I will check it.

Ok I am checking it

Did not work. I even changed the theme. The Top navigation is vertical AND I still get the 404 errors when I click the “Ask Question” button. Please take a look at the Admin backend

OK, then surely issue will be resolved.

I will DE-activate most of the plugins and see what happens.

Hello can you try in other installation, as there are lots of plugin installed, so someone is adding extra rule before every anspress rule, which is a cause of this error. I will suggest you to try in other fresh install (or existing install) but keep in mind that installing other Q&A plugin in same site may result the same. cause we use same post type and rewrites rules for posts.
