This has turned into a nightmare of many hours, most or all of it centering on Articles. The history:
-being just experimenting with MODX, I originally installed into shared hosting at /public_html/modx
-I briefly tried out Articles
-I really liked MODX and so started developing an actual site
-I eventually moved [i.e., copied] all the MODX files to /public_html, and correctly edited the *several* config files. Everything seemed fine, until...
-using Quip as a standalone, I discover it won't send notification emails. I see that it *sometimes* wants to use the old installation
-I uninstall, remove, and reinstall all the extras several times, trying various things
-I discover yet even one more cached config file* (do they ever end?)
-I try most everything here:
http://rtfm.modx.com/revolution/2.x/administering-your-site/moving-your-site-to-a-new-server
-now... when I click on almost any resource to edit it, I get only a completely blank screen (except for the one page using a static resource). However, the error log gets a new entry then: "[2013-10-27 15:10:39] (ERROR @ /connectors/resource/index.php) Could not load class: ArticlesContainer from mysql.articlescontainer." It's looking for Articles though Articles isn't called on any page anymore and in fact has been removed.
It seems that Articles has its tentacles into places that do not get removed when Articles is uninstalled and removed; and Articles gets registered somewhere and does not get that deleted.
So that's part of it, I'm posting this here so the next poor victim might get some insight.
Some other things: Articles gave errors on the fresh original install, similar to here:

I've also seen this: "Could not load class: quipNotifyComment from mysql.quipnotifycomment." I wondering if Articles and Quip share code.
* /public_html/core/cache/setup/settings.cache.php still had the old locations
