Links to questions are not generated properly

Greetings from Russia, comrads!

Thank you for great work and real ability to customize AnsPress!

I’ve installed it on site: https://www.math.vsu.ru/wp/?page_id=191

However, links to questions are not generated properly. To realize it you should view source of the page. As it is a production site, a had to provide dirty kostyl with javascript, but please, look at the source! Moreover, searching questions is not working (and I had to disable it with css, look to source).

Maybe the issues are caused by wrong settings I done, but I haven’t found any ability to reset the setting to defaults (even reinstalling the plugin).
