Hmm, very wierd. Please check your setting of NotifyTopicName in configure. Might be an idea to paste a (filtered) copy of your LocalSite.cfg here.

Our WebNotify process seems to be working fine, but I'm not sure what you mean by checking the topic in configure. Can you clarify?

Here is our current LocalSite.cfg.

$TWiki::cfg{DataDir} = '/opt/www/wiki/data';
$TWiki::cfg{Password} = 'blahblahblah';
$TWiki::cfg{Site}{Lang} = 'en';
$TWiki::cfg{LogFileName} = '/opt/www/wiki/log20 Jul 2007.txt';

$TWiki::cfg{DebugFileName} = '/opt/www/wiki/debug.txt';
$TWiki::cfg{ScriptUrlPath} = '/bin';
$TWiki::cfg{Site}{FullLang} = 'en-us';
$TWiki::cfg{Site}{CharSet} = 'iso-8859-15';
$TWiki::cfg{Site}{Locale} = 'C';

{NotifyTopicName} is one of the settings in configure. Please check it and make sure it's a valid topic name (it should usually be WebNotify)

I found that if {NotifyTopicName} is not set, you could get the error you give above. However this seems very unlikely to me.

You should also try downloading the latest rev of the plugin and checking if it still fails.

I'm sorry. I'm no longer able to debug this error as I've left the company to start my own (KangarooBox). I'll point this thread out to my successor in hopes that he has more luck.

Thanx! Richard

No feedback from reporter and no sign of a repeat, so closing.
