Not exactly. We encourage conversations that don't include login details to be posted here. If they involve bug reports or feature requests, it's better to post them in the forum below this on the home page.
In your PM you mentioned that you got the invalid namespace ID global error message. As of 2.1.0, the setting it refers to no longer uses the forum ID, but instead the 0 - 6 numbers on the left column of the Namespace Manager. In most cases, this number should be set to 6.
Once that's done, I recommend checking each of the namespaces in the Namespace Manager to be sure that the correct forum is still associated with each namespace. When this is all okay, click "Rebuild All Namespaces" at the bottom of the Namespace Manager.
There are a lot of new tools to check out since 2.0.0, so you may benefit from having a look at the
VaultWiki Manual, especially since I know some of the settings have changed.
After you finish, please report back what additional steps you have had to take that were not covered by the upgrade script, so we can try to improve the early-version upgrade portions. I suspect that a number of folks will be trying the same kind of multiple-version upgrade as you when 2.5 is released later this week.
