Why does scrolling work in the component only after I update its cache (Bitrix)?

Question

caching

Hello!
The site is based on Bitrix, on the main page there is a bitrix:catalog.section.list component that displays categories prntscr.com/g3ha9e
But scrolling does not work on it. And it starts working only when I log in as administrator and update the component cache in edit mode. I have already done clearing the cache files, but the situation has not changed. What could be the snag?

Answer 1

The most probable problem: you connect the scrolling script in template.php itself.
So it turns out that the script is there when the cache is reset and the scrolling works, and when the cache is already built and there is no entry in template.php, the script is not connected.
Put template.php on pastebin.com and I can tell you how to fix it
