1: Error searching specific words -BUG?
Posted by Yves Goldberg on 07/07/04 01:55 PM
When I search specif words ("yves" or "welcome" for example)in my 5.1.1 version I get an error message as below. For all other words it works fine.

It seems to come from the last line in /forums/tcl/forums-sc-procs.tcl

Is this a BUG because a default value is not provided to db_string or could this be something else?

Thanks.
