Page With Different Styles

Hello!

I’m working on a client’s website and they moved it to another subfolder. After that, the pages are all broken.

Very strange because on the page builder it looks good.
See here:

It’s not a cache problem and I deactivated all plugins already. I’m not able to fix this and need to do it asap.

Can you help me please?
Any hint?
