WooCommerce randomly clearing out shipping dimensions

@bryantbilliards This sounds like it may be a conflict elsewhere. If you have the USPS extension sold through the WooCommerce.com marketplace, you can create a ticket to have us look at this further.

If not, it may be a conflict with another plugin, and we suggest testing through the steps here:

In either case, this sounds like more of a general WooCommerce issue, so it would be best to create a thread in that forum if you’re not able to do the above:
