Thread:Talk:Validator/Error on Validator

Hi Since I updated SMW to 1.8.0.1 and validator 0.51, I have serveral times the following message on my wiki on most of the http://stargate.wikkii.net/ articles: Warning: file [function.file]: Filename cannot be empty in /home/stargate/public_html/wiki/extensions/Validator/includes/definitions/ParamDefinition.php on line 956

Does anyone have an idea about what's going on?

Thank you.
