yeah its a code. But not able to remove. When i place cursor on the code , it creates another popup. Thats the problem.
Either find your template in your control panel and search for "pop" ".js" "open" and scroll through the code to see if you see anything suspicious, if not, you're better off reuploading the template, and restore your config file with rewards etcetera, depending on the script your using.
If your trying to get the source code on your website using element inspect, use popupblocker+ or torbrowser to prevent popups.
