Please tell me how to check the question that I have posted in the past.

I’m still vague on your question. If you want to change the question that you posted in the DesignWall site. Currently, our plugin disabled temporary the profile page and you can not find the old question. We are checking and improve the profile page with the DW Q&A in the DesignWall site. If you have any issue or question, you can create a new question and we will check and help you resolve it.

In case that you want to find the questions from your site, you can find here for the document guide on how to configure a profile page and display all the questions of user: https://www.designwall.com/guide/dw-question-answer-plugin/buddypress-integration/
Hope this helps!
