Hi,
on product edit page, on the status Tab
there's the AcyMailing affiliate link
<a target="_blank" href="https://www.acyba.com/?partner_id=19513"><img title="AcyMailing2" src="https://www.acyba.com/images/banners/affiliate2.png"></a>
The image link: https://www.acyba.com/images/banners/affiliate2.png (https://www.acyba.com/images/banners/affiliate2.png) is broken
I wrote about this before 3 years too :D
But nothing heappend still....
I routinely override product_edit_customer.php & remove the Acyba link. Saves the client (shop owner) getting ideas about adding more complexity to their store!
Yes, we use only Acymailing not mailchimp or other - ist the best and we have a lot of custom plugins for Acymailing and VirtueMart together.
