paka, from what I can see there's no visible ads on your website for myself, nor can I identify any areas in the code that would allude to third party script injection. Have you checked that your browser hasn't been infected with adware? Have any other members on your forum reported the same occurrence? Quote paka
No wonder UCOZ is banned from facebook. Anyone can doo on the page what he wants.
I would also just like to reinforce that nobody is able to edit the template code of your website without having either the appropriate permissions granted to them in Users, or alternatively, having gained access to or knowledge of your account security details via means outside of our control.
