What have you changed since the last time profiles worked? Have you updated AnsPress? Have you installed new plugins or updated old ones?
The simplest answer is you author archive page is disabled by your SEO plugin, if you are using Yoast SEO it is automatically set to disabled so you don’t get page duplicate. Flow this guide to enable it: How to disable or enable the author archives. If you are using other SEO plugin do a google search.
