Theme for Multisite

Thank you but the theme is already enabled in the Network Admin dashboard and already activated in the Main site dashboard.

The Network Admin dashboard doesn’t show any “Appearance-Themes” button on the side bar.

Any idea what is happening?

Thank you Bet. I can’t get into the subsite dashboard. When I click on it the page doesn’t open. I get this error:

herbax.org redirected you too many times.
ERR_TOO_MANY_REDIRECTS

How can I fix this?

Thank you again Bet. This is my wp-config.php Do you see something could be missing here?

Thank you for the advice. I am new to wordpress multisite and i am trying to figure out how this work. I appreciate your help.
I couldn’t find .htaccess so i created one. I uploaded to godaddy but there is no code, it is a blank file. I decided to copy and paste a code i found in the forum. Do you think that’s OK? Here:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
