If you go to the MyBookTable dashboard (click the MyBookTable menu entry on the WordPress admin menu) and click the “View your Book Table” link, that should take you to the page that has your books listed on it. If it does not, it is most likely because you have an incompatible plugin or theme on your website that is interfering with MyBookTable. Please try disabling your other plugins and switching to a default WordPress theme, and if this causes the issue to go away, try re-enabling the plugins and theme one at a time until you determine what is causing the issue.
