I have collapsing boxes throughout my site, same structure on every pages. When in preview every thing works nicely but when I go on my published site only one of the pages works correctly.
I have went through the code of all the pages again but can not find why!
page where it works: https://www.charlesdubois.co/measures
one of the page where it does not: https://www.charlesdubois.co/planes7
Any help would be much appreciated
