MY WP ADMIN PANEL NOT WORKING AFTER LOGIN

Your site has mixed content warnings. It’s loading as https, but many of the assets (probably including your admin’s CSS) is loading as http, so the browser won’t actually load it.

Edit your site’s .htaccess file and add these lines at the top:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]
Header always set Content-Security-Policy "upgrade-insecure-requests;"

Use your hosting control panel’s file manager to edit .htaccess.
