>This is quite exceptionnal. I do not have any CGI link into the site since last night. And, that one, it was converted three days ago. Can you login again, click on Search, and send me the view source of the search page (the one with all the seach criterias). I will verify first to see if you are having the proper page. Also, before doing this, can you clear all the temporary files and restart the browser?

I did all that, accidentally, and it works now. I probably had my browser open since last year without a restart, so it seems to have cached all sorts of obsolete stuff... and the search button works now, no wwwc link on it.
