Is there any places for Ads?

You could probably add them in yourself, but it will require some basic code editing.

Go to your /wordpress/wp-content/plugins/anspress-question-answer/theme/default/ folder and find the relevant theme file.

Then copy that file including the folder structure to your /wordpress/wp-content/themes/your-theme/anspress/ folder. This is so that you don’t overwrite these files when the plugin updates.

So for example, if you want to place an advertisement on the user profile page, you copy:

/wordpress/wp-content/plugins/anspress-question-answer/theme/default/user/user.php

to

/wordpress/wp-content/themes/your-theme/anspress/user/user.php

And add the advertisement code in that file.
