We are considering enabling this feature for all customers but this isn’t confirmed yet. For the moment, I installed a plugin called “CircleFlip Portfolio allow comments” and activated it. I also modified the file named “single-circleflip-portfolio.php” in the theme root to have the comments form ( I found that you made some edits already to this file, please be aware that those changes might be lost if you updated the theme without taking a backup of those).
I also enabled the comments on the blog post through the meta box in the Edit Post page.
Check it and let me know if you have any feedback
