Thanks for your reply. And I appreciate your informing me with this.

Wish you a nice day.

We're really sorry, but the wpDiscuz cannot be worked in such cases. There is no way to make it work via js.  

    I'm sorry for my poor English and poor coding ability firstly. So I would really appreciate it if you are so kind as to provide me with a simple code sample to fix the problem.

    My Wordpress Link is arek.index.city which I'm still working on it. I used an easy way to build Ajax for my website, which I will list below the post. The problem is, the first time I load the website, the wpdiscuz works just fine, but when I move into another post of my blog with my Ajax, wpd-editor-wraper and wpd-form-row disappear. I tried running '<script type='text/javascript' src='https://arek.index.city/wp-content/plugins/wpdiscuz/assets/js/wpdiscuz-combo.min.js?ver=7.0.10' id='wpdiscuz-combo-js-js'></script>' while Ajax finished, it works, however, when I click reply button it will reply for many times.

    Thanks again for your generous help.
