You can create your questions page like this: http://fluentthemes.com/wp/knowledge/questions/ by following the given instructions below –
At first, find ‘Categories’ sub-menu under the ‘Questions’ menu from your wp admin page. Then, create your question categories. These are the categories users can choose from, when they create questions using the ‘Add Questions’ page from the front-end. See screenshot below:
After that, if you want to add questions directly from you wp admin panel, please click on ‘Add New’ sub-menu under the ‘Questions’ menu and create as many questions as you want.
You will find some useful settings for the question just below the main text editor of the question. See screenshot below:
Finally, you will want to take control on the settings of the questions, since questions can be created directly from the front-end by the users of your site. To get those settings, you need to visit ‘Questions’ settings of your ‘Theme-Options’.
You can change the url of the question page by changing Question Slug, but it is important to remember that whenever you change the Question Slug or Question Category Slug or the Question Tag Slug, you need to visit the ‘Permalinks’ sub-menu from the ‘Settings’ menu of your wp admin panel and click on ‘Save Changes’ once again. Otherwise you may see 404 error pages instead of the actual questions pages.
Another important settings of ‘Questions’ is to choose the correct ‘Add Question’ page and ‘Edit Question’ page.
As ‘Add Question’ page you should choose that page, which was created using ‘Add Question’ template. And, as ‘Edit Question’ page you should choose that page, which was created using ‘Edit Question’ template. See details here to know how to create page using ‘Add Question’ or ‘Edit Question’ template.
