Problem with integration – DW Question & Answer plugin

Hi,
This is a great plugin – Exactly what I needed, thanks.

I work now with DW Question & Answer plugin
https://ww.wp.xz.cn/plugins/dw-question-answer/

On my test site I have set up the questions here:
http://sun.hp.intersol.co.il/dwqa-questions/
single post here:
http://sun.hp.intersol.co.il/question/test/

Only category page isn’t work
http://sun.hp.intersol.co.il/blog/dwqa-questions/question-category/questions/

The date does not come to the page (page.php)
Can anyone help me understand what problem?

Thanks,
Michael
