How to fix net::ERR_INCOMPLETE_CHUNKED_ENCODING after changing ownership of files on server?

Question

Nginx

In general, there is a site on vds with wordpress and it became necessary to change the owner of the files in the site directory, I went to www / html / ... to the desired folder with files and unknowingly made dirt, namely chown -R www-data:www-data /, thinking that this would only affect those nested in the folder files from which the command was executed. Everything crumbled. As a result, I returned the owner of mysql to /etc and its www-data site. And it seems that the site worked, but in the admin panel, pressing shift + f5, the layout fell down, and the browser on the GET request to load-styles/script.php issues a net::ERR_INCOMPLETE_CHUNKED_ENCODINGlong errlog where the scripts complain in this way

jQuery is not defined at wp-category-permalink.js?ver=3.2.3:51

etc. There is no such problem on the site itself, the log is clean. Where have I not cleaned up my dirt?
Server on Ubuntu:
PHP7-FPM/FastCGI
MySQL 5.7
Nginx 1.1

Partial restore is not a solution - you need to set everything from 0 or restore from backup
