My ninja forms signup form is being appended to each blog post, I contacted them and when I tried using the default wordpress theme, I didn’t have this issue but when I switch back to appdev, it appears again. The ninja team told me to go to you guys. All append options through ninja forms plugin is set to none. http://www.blazonmobile.com/index.php/blog-post/test/
On the post editor screen(page edit window) click on the screen options button on the upper right corner of the screen. This will open a fly down menu where you need to uncheck the box next to Discussion.
