WordPress的删除缓存postmeta

Question

I'm using Profi Search form and Advanced Custom field . Profi Search Form allows me to filter my posts through my custom fields.

The problem is that it's allows me to me to filter with fields I deleted through the interface ACF dashboard.

How can I permanently delete these custom fields ?

Ok, the two solutions I've found :

• Delete these posts meta in the database, with MySQL.
• Use a plugin like " WP-Cleanup " and delete revisions
