Hey Nik,
first of all, thank you for the purchase!
Sorry for this issue, it apparently arises because of the css conflict between the theme and the Disqus module. To fix it, please go to “Appearance -> Editor” and add the following line at the bottom of the “style.css” file:
#content iframe { max-height: none !important; }
Thank you for reporting, I will add this fix into the next theme update.
Should something else pop up, do not hesitate to contact me!
Sincerely,
Andrew | Satori
