I think its due to your theme, due to your theme CSS AnsPress description field is hidden. Please check CSS.

Yes. [anspress categories=”category_slug”]

Hope your issue solved. This issue is happening due to your theme comment template. I am working on a fix which will prevent theme to override AnsPress comments.

Will think about it.

You are using PHP 5.4 and that is a version of 2012. Try to upgrade to 5.6 or 7.

Download this version: https://github.com/anspress/anspress/releases/tag/2.4.6

Enable WordPress registration.

Its already in AnsPress. When you mention someone a notification will be triggered for that user. But currently AnsPress does not show name suggestion.

Default reputation cannot be deleted.

Make sure that new page is selected in AnsPress option. Save AnsPress option once. Also remove old ask menu link from menu and re-add it.
