This means you have an older version of the Enthusiast Anti-Spam Addon. You will need to upgrade to the latest version.

The domain supplied in your fanlisting URL in Enthusiast may be wrong or, if you’ve recently changed servers, you may need to change it to the right one. Until you correct it you need to open up antispamconfig.php and change:

$checkrighturl = ‘Y’;

to:

$checkrighturl    = ‘N’;

Sorry, Wordpress converts quotes. Make sure they are not curly single quotes.

Upload it to your main Enthusiast folder after.
