how to get https://subdom.example.com/wp-login.php so i can edit the subs.
error 404.

i started with 3.5.1 to get multisite. all WordPress installation straight into public_html/ and its mean on root right?

it doesn’t show anything at https://subdom.example.com/ , its just show Index of/

That means you set up subdomains wrong on your server.

They should point to where example.com has WP installed, NOT their own folder.

my host server, when i created subdomain, its created a folder called subdomain name. right exactly at public_html. so my public_html now contained :
subdom folder
wp-admin folder
wp-conten folder
wp-include folder
and other files from wp installation.

i dont know is there other host server do the same about created folder on behalf subdomain.

i thought so about wrong pointing the folder. but my MS installation for subdomain NOT subfolder.

so what other wrong ?

my host server, when i created subdomain, its created a folder called subdomain name. right exactly at public_html. so my public_html now contained :

You don’t want to point to a folder, you want to point to public_html
