Hi, there seem to be issues with your plugin with regards to the widgets.
Take Popular_Question.php, line 52 (in Version: 1.2.5).
You are using the function get_the_author_posts_link() to retrieve and display an author name and link. Yet, you also have an option within the plugin to allow questions and answers from anonymous users. In these cases, there is no WP User for get_the_author_posts_link() to retrieve. This leaves a blank space for each question listed, making the widgets look broken.
(Also, your website’s login/signup functionality is broken. New registrations don’t result in emails being sent out, and the Google login doesn’t work)
1/ About the widgets, we will check and update it in the next version.
2/ About the login/signup on our site, we have checked and fixed it.
