Site-wrapper / footer is different on one page

Hi all, I have been implementing some changes to the site, added some code on particular pages and in the advanced editor, so far so good. That its, until I noticed that it works well EXCEPT on one page: Discography. Here, the footer took the transparency rule, but doesn't seem covered by the linear gradient of the body. On every other page it is fine. 

After digging in, I saw that on the Discography page, the .footer-sections was not comprised in the .site-wrapper, like on all the other pages.

Obviously there is no access to the HTML in order to manually move it. 

Would anyone know how to fix this? 

Thank you in advance!

Update: it was related to one broke line of code in one of the code boxes on the page. (as small as one extra </div>). If anyone has the same issues, check your code.
