Subfolder multisite issue. Themes and plugin files 404

The .htaccess looks fine. It is exactly like the one I have. Do you have any .htaccess files inside /wp-content/ or /wp-includes/ or one level up from the main site folder?

Also try deactivating all plugins.

I also found this topic that seems to be for the same issue. From what I read, there was a situation caused by hosting security measure in which the .htaccess file was not used and it was needed to do changes in the apps/wordpress/conf/http-app.conf file. This is the exact post I am talking about.
