As title says. I've created the bare basics of a custom site definition (no features etc.).
It, at least appears, to deploy and activate fine judging by VS 2010 output.
If in central admin, I can see this available custom site definition (and many more) in the site actions > new site dialog if I open this dialog from central admin - but not if I'm actually on my site (publishing site).
Why have I lost visibility of many of the site templates both OOTB and my custom site definition?
Also - this doesn't matter so much if it's only a case of the site definition not being visible - because I ultimately want to create a site from this site definition programmatically so as long as I can still do this it's not a problem.
