Using the Joomla autoupdater i get the error messages shown on the Extension Mgr Update screen. See also attached screen shot.

I checked our business version subscription and added in the client domain sag.org.au - and then purged and refound the update with no change, and then waited an hour and did the same purge and refind the updates with no change.

Is there a periodic update on your servers that I need to wait for before the auto update will find the registered domain?
Is there an issue with this being a subdomain of the client domain?
Can I just install the new version over the installed 2.5 version as an alternative upgrade method?

Thanks for your assistance.

Thanks Nicholas.

I thought I read elsewhere that a subdomain such as j3.sag.org.au should be recognised when the base domain such as sag.org.au was registered as the subscription domain. Certainly I would want to be able to get automatic updates on both.

In this case I did the install of the 2.6 version over the top of the installed 2.5 version without any apparent problems.
