Thanks for using our theme.
We do not give a guaranty for full theme compatibility with all existing 3rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our basic support.
You can post your request about compatibility with the plugin here – https://www.8theme.com/taskboard/ (do not forget to mention the full plugin name and link to its site), so our dev team read it. If it takes votes from other customers, our dev team will add it in one of the next updates.
