Hey! I created a wiki a few months ago with the UPC updates. I found something on how to add tabviews to pages, and tried it out. When I wrote the code in source editor, there was no new color it showed up as, and when I saved, it just showed up as regular text. I tried redoing this multiple times, to no avail. Is this function available on updated wikis, or am I doing something wrong? [|My wiki]
