Donncha — great plugin and thank you so much for all the work you do
I am having a pretty serious issue (for my site) with .5, however. It appears that it breaks any functions related to detecting if a user is logged in (on the domain mapped site).
E.G., on a domain mapped site I use the template tag which should display “Login” if the user isnt logged in, or “Logout” if they are. Regardless of how many times I log in, it never detects that the user is logged in for the domain mapped site — only the “original” blog (I am using the feature you added in bullet number 3).
That feature is awesome, by the way, because it allows us to purchase ONE *.blog.com SSL certificate, and all of our users can manage their content that way, but on the domain mapped site, it doesnt seem to be dececting credentials.
