Implemented rename meta key "fpd_data" to "_fpd_data" O Oval started a topic over 7 years ago Please rename meta key "fpd_data" to "_fpd_data" with "_" prefix which mark it as "hide" meta. Many plugins try to show it as variation meta.
Included in V3.4.9
seems it is not all the files changed correctly
i.e.:
/woo/class-wc-product.php
and
/woo/class-wc-cart.php
they both operate only with "fpd_data" meta key (era before 3.4.9)
