Enable WordPress Plugin, Theme Updates and Pretty Permalinks on Nginx

WordPress doesn’t know that your Nginx web server is capable of doing URL rewrites without mod_rewrite and Apache, so we explain that by adding:

add_filter('got_rewrite', 'nginx_has_rewrites');
function nginx_has_rewrites() {
	return true;
}

in your theme’s functions.php.

It is very likely that along Nginx you are also running PHP-FPM for all your PHP needs, and for some reason WordPress thinks its PHP process can’t write to disk. We tell WordPress that it can:

add_filter('filesystem_method', 'nginx_make_filesystem_direct');
function nginx_make_filesystem_direct() {
	return 'direct';
}
