I see this in Setup > Addon Modules. I use MailChimp; is it safe to delete the legacy module and am I correct in thinking it's the one shown in module/addons/admin?
Cheers
From September 1st 2017, Skrill are discontinuing the legacy moneybookers.com endpoints. This is used by the "Skrill" payment gateway module in WHMCS 7.2.3 and earlier.
If you are using the Skrill payment gateway module, it is important that you apply this update prior to Sept 1st 2017 to avoid any interruption in service.
