Thanks phranque, I was messing around with RewriteRule at one point, maybe without the right chunk of URL. IfModule was in there when I pulled it off the server. I'll try to figure out what put it there, possibly theme or plugin related.
lucy24 - The site was on a MedFusion (now Intuit Health) CMS before we replaced it with WP. I had no access to the CMS or Server before we re-pointed the DNS, so who knows where it came from. I only noticed it sitting in the Webmaster Central error report . . . along with >600 other URLs. So evidently someone or something had linked to it at some point.
I'll post more on this tomorrow. There's something else weird going on with which portion of the repeating URL chunk is being interpreted by the directive.
