I think I've got the problem with displaying the last posts in the sidebar sorted out.
vBulletin is a very robust forum program so I naively thought it would be an easy task to show recent posts in the sidebar. I've had them on the front page for the last year and coded that myself.
It turns out that a number of other forum administrators have tried and failed to do the same thing. When other features are added the code chokes on itself and you might have been denied access to sections of the site that you had visited many times in the past. Even as the site owner I was denied access so I knew there were bigger problems.
Judging from the discussion in the
vBulletin support forums, it is easy to display the last threads but it exponentially more difficult to display the last posts with a link to that last post and only posts from those forums that have public access. The coders among you will either yawn and think we are a bunch of hacks, or you'll appreciate that when you're dealing with literally hundreds of hooks, templates, functions, variables and other undefined things that go clunk in the bowels of remote servers that sometimes things just take longer than you'd expect.
Changes in software versions and other addons and modifications to forums make it even more difficult to write a one solution solves everything for all of the admins that are using this software.
I think I finally got it sorted out, if you find a problem please let me know. Thank you for your patience and contributions to this forum.
