PLESK CENTOS & NGINX WPMULTISITE

My server run PLESK CENTOS & NGINX WPMULTISITE

I create a subdirectories multisite network and got problem :

links for theme or plugin search with subdirectories and not root wp-content ! if a subdirectories is "aaa" it search theme data under aaa and not root wp-content.

What is the solution please to make this network works correctly ?

Thank you
