wpsso plugin removed but still installed help need it removed


please can someone help me remove this, have uninstalled this but it is still showing as an authorship on my posts

I’m not familiar with the wpsso plugin, although I was wondering if it had made any amendments to your theme files and/or database.

Does the plugin still appear in your listed plugins inside WordPress?

Dear Jo-Anne,

Have you sorted this out?

If no, please remind me a URL that keeps showing the plugin so I can have a look for you.
