full width has no left/right margins

Hi…my client’s site “pointarena.net” has many “full-width” pages, and they worked great, with a left/right margin (so the text was not flush to the browser window), but all of a sudden, it stopped working. I assume this is due to an update, but i am using a child them, and cannot seem to find a solution to rectify this problem. I listed the impacted page above, but all full-width pages are impacted,
https://pointarena.net/shop/
https://pointarena.net/eat/
https://pointarena.net/stay/
https://pointarena.net/services/
https://pointarena.net/explore/
https://pointarena.net/find/
https://pointarena.net/events/
https://pointarena.net/calendar/
https://pointarena.net/fyi/

thank you!!
