Wikidot Community

I've been on Wikidot.com for quite some time and am the master admin for several wikis. However, it's been a few years since I have actually created a new wiki.

A few weeks ago I created this wiki, picked the same theme as an older wiki, and expected to just copy and paste a bunch of code from the old one to the new, with just minor modifications.

However, the new one seems to be missing auto-generated system pages. For example, there seems to be no "admin:manage" any more (meaning that I have to change the admin settings via my user panel) - and there also seem to be no "system:page-tags/tag/…" pages. I used the same code for a Tag Cloud, but when I click on an individual tag (whether in the cloud or at the bottom of a page), the wiki tells me that the page does not exist.

So… I assume that something has changed when creating new wikis in the last few years. Can anyone tell me where to look in the documentation of how I can rectify this problem? The lack of tags in particular is annoying.
