The lack of sidebars that you are seeing is happening because you have MyBookTable’s Theme Compatibility Mode turned on. This mode works by using your website’s Page theme template on MyBookTable pages in order to make them fit better with the rest of your theme. It appears that your theme by default does not show the sidebar on pages, so that is why it is not showing that sidebar on your archive pages. You can try turning off Compatability Mode in the settings, but this may lead to other worse visual problems on your MyBookTable pages.
We have done a lot of work to try to make MyBookTable as compatible as possible with as many themes as we can, but it is impossible for us to support all WordPress themes out of the box. The only way for you to have 100% compatibility with your theme is to create custom PHP templates that allows MyBookTable to integrate with your theme’s style. You can read more about this process on our wiki here.
