Hey @alecocco93
Thanks for contacting support.
Most of the time this issue caused because you cannot use the “Any Size” or “Any Color” or “Any Anything” or any duplicate options when listing items to eBay. This is an eBay limitation not a limitation of WP-Lister. You can read more about this here –
http://docs.wplab.com/article/134-about-variation-attributes
You will want to focus on the section titled “Why exactly can’t I use variations with “Any Color…” selected?” section.
You need to select a unique variation name or NameValue for each variation so if there are more than 1 variations with the same names/options those will need to be changed so each variation combination is unique.
If this is not the issue, then please open a ticket here: https://www.wplab.com/request-support/ and provide your dashboard URL, admin login credentials, and a sample SKU for us to examine for you.
Kind regards,
John
