You're likely displaying that content in <pre> tag and you're using HAML. You see, <pre> tag is space-preserving and HAML is space-sensitive.

I had a similar problem a while ago. IIRC, haml indentation level is somehow added to all subsequent lines of content being rendered.

My memory is blurry on the details, but this is what appears to have fixed it for me, HAML's find_and_preserve helper:

= find_and_preserve(item['content']).html_safe
