Fix notices

I was all set to make 1.2, did a final test, and discovered there's all sorts of notices on the topic pages. Ugh. Pasting here until I can deal with them. If anyone else wants to jump on this, feel free.

These are in UR but noting here so I can see if they're something I need to fix before release.
