hmph....
all four editor plugins (codemirror, JCE, none, tinyMCE) are enabled and Global Configs indicates JCE as default editor
site has JCE 2.2.4 installed (v2.3.1 is most recent stable release so it's not that outdated. Seems that it was working on site at one point and now is not??)
I can provide access if necessary...
