FVM custom fields on multisite

Those fields appear to be from version 2, so pretty old.
On v3 simply deactivate and delete via wp-admin.

If there are v2 leftovers, run via phpmyadmin or your database tool.
Please backup first, of course.

DELETE FROM wp_options WHERE option_name = 'fvm_settings';
DELETE FROM wp_options WHERE option_name = 'fvm_last_cache_update';
DELETE FROM wp_options WHERE option_name LIKE 'fastvelocity%' OR option_name LIKE 'fvm-%'
DROP TABLE IF EXISTS wp_fvm_cache;
DROP TABLE IF EXISTS wp_fvm_logs;

Replace wp_ with your tables prefix.
