Hi @webmaster1234,
Do you happen to be using a shipping policy from eBay in your listing profile?
If you are using a shipping policy, that will override any and all shipping settings that are set in the listing profile or edit product page. So, the first thing I would check is what is the unit weight set in Woocommerce for? Is it pounds, ounces? It needs to be set to whatever the weight unit is on the eBay marketplace you are listing to.
So, if the eBay marketplace uses pounds, it should be set to pounds in your Woocommerce settings as well.
Secondly, if you are using a shipping policy you can try disabling the shipping policy and momentarily using settings set up in the listing profile, if the error clears, then you know it is some setting in the shipping policy which needs to be fixed, in that case, you would fix the policy on eBay, then refresh your account details in WP-Lister, then verify the listing.
