Tried a number of times to edit the sidebar (blogroll) and got this message:
Sorry! There was an error: Can't evaluate the expression because the name
"referer" hasn't been defined.
The error was detected by Frontier 9.0 in mainResponder.respond. Webmaster: Time: Sat, 09 Aug 2003 23:35:04 GMT.

It sees me as an editor, lets me into the area to make the edits, but then
the above occurs.

Any ideas?  Thanks in advance.
