Css and js not working on Wordpress multisite

Hi, I moved my whole WordPress Multisite to a new server and after the migration the css and the js don’t work. IT seem to be a file access error. But I’m not sure how to solve it. I’ve read that I should probably edit the functions.php, but I’m not sure how to do it and if that would solve the problem.

I appreciate any help, thank you so much.

Hello there,

Did you mean CSS and JS stored in a third-party plugin? Please refer to this codex to check wether you’ve done proper site migration.
