I inherited a Discourse install that I am trying to just keep running. I got an email recently saying that I should upgrade to 2.5.1. There was a link advertising an easy one-click upgrade, but when I translate that link to my sandbox site it says " Oops! That page doesn’t exist or is private." (I am logged in as admin and can see the admin dashboard). When I clicked on the link for the release notes it took me to the release notes for the 2.6.0 beta, not the 2.5.1 release. Are these the same?
The admin dashboard says this is a critical update, but doesn’t provide information for how to update it. I’m concerned that my installation might be misconfigured or something. Is there some other mechanism for initiating the upgrade, or something I should fix with my installation so that the ‘admin/upgrade’ path will take me to a page where I can initiate the upgrade?
