SID-00197: Getting ERROR: bad Map expression

Status:	Answered	TWiki version:	4.2.4	Perl version:	5.10.0-37.6
Category:	CategoryPlugins	Server OS:	SuSE Linux 11.0	Last update:	16 years ago

This just started this morning, and I have exhausted all of the ideas I have gotten from searching in here. I'm sure it is some sort of user error, but I have no idea what it could be. I would be very grateful if someone could simply give me an idea of where to look.

Thanks, Peter. I had found those entries, but none of them applied in my case. (I did have some topic names containing a dash, and did a lot of work renaming them and changing all of the references, but that did not cure the problem.) I ended up looking through several hundred topics before discovering a file name in that web directory that looked like a network file reference (\\xxxxx\xxxx\xxxx\xxxx). Having no idea what it could possibly be (or how it had gotten there), I crossed my fingers and deleted the file. The problem instantly vanished.

(The painful part was that the server was remote, and I was limited to a 128K ISDN connection from my location. I had to SSH into the server and use MC to examine and edit the pages.)

My problem is fixed.
