How to load the correct css from the server?

Question

css

Help me please.

I had to add an extra. functional.

There is a section on the site

https://tourcroatia.co.uk/packages/unesco-heritage...

You may notice that everything is displayed strangely. That is the problem. If you pass the nocache get parameter to 1, then everything works

?nocache=1

Site on wordpress, cleared the plugin cache. New js works fine but css doesn't.

There is an .opcache folder at the root. but I don't think it's the case (there are binaries).

Help plz. Beg. Feel free to ask questions if I didn't mention something.
