Hi @callfaad,
After installing the plugin, please go to the “General clean-up” tab, then search for the row containing “Orphaned comment meta”. You can then delete them by selecting the corresponding checkbox and clicking on the “Delete” action.
However, please make sure to have a look and verify if they are really orphans before deleting them. And also make sure to backup your database first before you delete anything. In case something went wrong, you can restore it 😉
Best regards,
Younes
