Of course – only looking to ensure @benubikim gets support for the issue described!
@benubikim,
Thank you for reaching out to us here. First, I would like to mention that you and all of our users are always welcome to reach out to us on the support forums here or via our support form found here.
Before removing the plugin you will want to deactivate it in the WordPress plugin panel. Clicking delete should then fully remove all files under /wp-content/plugins/feeds-for-youtube/. If it does not, there may be issues with folder permissions on your particular setup which your host should be able to assist you with. If you are referring to specific database entries not being removed, you may need to go to Feeds for YouTube > Customize > Advanced and disable the Preserve settings when the plugin is removed option. Once this is disabled, you can delete the plugin and it should also clear any saved Database information. This is enabled by default to ensure users reinstalling the plugin do not lose all of their connection settings.
If you have any other issues or feedback at all then please just let us know as we are always striving to improve the plugin and create a better experience for our users ??
Joel
