A stupid simple plugin that will clean up unused ACF meta fields.

Remove post or meta data that's been abandoned by a deleted ACF field.

Download as .zip and drop into your plugins folder. Install, and it's available under Tools

• Cleanup of code and slight re-organization.
• Deletion of term and comment meta.
• Nicer layout.
• Addition of nonce
• Check against local ACF json includes (currently database saves only).

I quickly threw this together and is not yet toughly tested. Backup your database first.
