Vanilla 1 is no longer supported or maintained. If you need a copy, you can get it here
When an error occurs after starting a discussion or adding a comment, like no discussion title or comment too long, the error page is not displayed. The member gets directed to 'http://mydomain.com/discussion//'
. My Vanilla is placed in a subfolder but accessible through the domain directly. I guess it has something to do with that? How could I alter the settings or the .htaccess to display the error page?
