Hello Vintage_Egypt -
I am sorry to hear that you have run into difficulty with posting a listing.
Please be aware that the message you have included here is a Warning which would not prevent the listing from posting, but there is likely another message from eBay's API indicating the reason the listing did not post. Please review the notifications area of your account for the listing title and it is likely that you will find another message.
If the message is unclear or you continue to have difficulty, please feel free to file a support case from under the Help tab of the site and our support team will be happy to look into it for you.
