White screen

Whenever I click on the plugin, it takes me to https://inkedfur.com/wp-admin/admin.php?page=stock-manager which just loads a white screen. I’ve tried uninstalling and reinstalling with no luck.

Also, why isn’t this under the Products tab. I see no point for it to have it’s own tab with a generic gear icon. Would prefer it under Products.

Thanks!
