What determines whether or not the following is true?
At some point after upgrading to 1.2, the link to account/upgrades disappeared from the user control panel and from the navigation visitor menu. The page still worked if you brought it up manually, but for some reason the link wouldn't appear. I am running the old Advanced User Upgrades add-on that allowed people to buy upgrades more than once, but disabling all add-ons (in config.php) and going back to a stock skin didn't fix it. Also flushed memcached, the opcode cache, etc in case there was something weird going on there.
I've removed the conditional from the template in the meantime... and that fixed it. But not really sure how/why I ended up here in the first place. Thoughts?
