Why does a part of the code crash after uploading to the server?

Question

FTP

Good day, guys, I have such a question... I
updated my design on the site, registered a couple of js-ki and css, then I start uploading all these files to the server.
Here is a screen,

After uploading, the file size remains the same, and the site is full of game. The server cuts off part of the written code after loading, tell me what's the catch? I'm puzzled... (p.s. don't throw tomatoes at me)
