There is a little bit of mess on where Update Manager is running and where plugins are looking for updates.
Classic Commerce
Since version 1.0.4 it’s looking at officialplugins.classicpress.net
that does not exists as subdomain, but the right endpoint lives happily at classiccommerce.cc
.
With Add plugin release Update Manager Client by xxsimoxx · Pull Request #347 · ClassicPress/classic-commerce · GitHub I’ve updated the client and, pointed to the right images without modifying the client and added opt-out for statistics.
CC Compat with WooCommerce
It’s looking at classiccommerce.cc
.
Don’t know why but it’s hiding “view details” link in plugins page.
Classic Seo
In version 2.0.1 itìs looking at www.cpseo.net
but the domain is not configured and seems that no Update Manager is running on it. But with Add new update server to Update Manager by timbocode · Pull Request #136 · ClassicPress/classicpress-seo · GitHub and so on the next release will look at officialplugins.classicpress.net
.
