Table Error – Plug-in Not working

Hi, I’ve installed the YITH WooCommerce Product Add-ons & Extra Option plug-in free version to test out and its not working.

It lets me add an option and click active but its not showing on the product page. I also have this error: WordPress database error: [Table ‘countryandcastle_comwordpress.www2_yith_wapo_groups’ doesn’t exist] SELECT * FROM www2_yith_wapo_groups WHERE del=’0′

My Theme is Astra – which is very popular so I’m not sure its the theme.

I installed from the add plug-in within wordpress (not manually)
