I just completed install of my Pligg site and less than 2 hours later I had 4 spam user accounts register. I have on recaptcha, human check, spam trigger, askimet. they did not post stories. I know these accounts are spam because we made no announcements and there wasn't even content on the site.
When I enter the site, it shows "Could not open templates/./modules/captcha/lang.conf", but I can still login to admin area, and after my login the front page can be show properly
