Block not appearing when expected

Thanks for getting back to me.

>> Have you altered the default View at all?
No.

>> Are you filtering by content type?
No.

>> Or limiting by vocabularies?
No.

>> Have you changed the configuration of the block from the admin/build/block page? Perhaps limiting the pages on which it appears?
No -- triple checked!

Just to be sure, I uninstalled the module, deleted the view, the reinstalled the module -- same problem.

In an attempt to learn more I created another node from scratch...

Node 3:
- Content Type = page
- VocabularyA: Term1
- VocabularyB: Term2

Now the "Similar By Terms" block appears on Node 2 and Node 3 -- so there's nothing wrong with the view or block or content type or terms or vocabulary. Very strange.

So maybe Node 1 is an anomaly -- some aspect of it is corrupt? So I deleted Node 1, then recreated it from scratch (same title, menu path, content, blocks, terms, settings, etc.). The "Similar By Terms" block is now present -- problem solved.

As far as I can tell the Similar By Terms module is behaving perfectly (I love this module) on all other nodes, so I'm chalking this one up to a "bad node".

Thanks again. Closing.

It's the first "bad node" I've ever seen. Bad, bad node. Wish I could prove it.
