2. For the ads issue on autoload, i notice you’ve been making some changes for the google ads, right? You may need to recheck again your code because on autoload the ads on the next article is missing. I mean the content of the ads.
4. For the captcha, it would be better if you contact the plugin author regarding this issue, because i’m not quite familiar with that plugin yet. Also, we don’t provide full support for 3rd party plugin. But we will always try to help our customer as long as we can.
