I just installed WP on a new domain.

Firstly I used a One-Click install.
When I set up, page looked like the CSS was not loading and it would not allow me to login.

I then deleted this install, database etc. and did a clean manual install with a fresh download of WP 4.9.7.

Same issue.
Setup Page loaded as if the CSS was not loading and once install complete not allowing me to log in (same CSS issue).

Am using same server I have multiple WP install running so should not be a server configuration issue as all other sites are perfect.
Broadband speeds very fast so should not be that.

Any ideas?

PS. I am not new to WP and have been using it since version 1.1

If you currently have an SSL certificate for this particular domain, try adding the following to your wp-config.php:

define('FORCE_SSL_LOGIN', true);
define('FORCE_SSL_ADMIN', true);

If that isn’t the issue, there could be some script concatenation issues or something else entirely. Try the following next (the second will display some debugging information on script loading):

define( 'CONCATENATE_SCRIPTS', false );
define( 'SCRIPT_DEBUG', true );

It was an SSL/mixed content issue.
Don’t know why as I have used the same install many times with no problem.

Sorted now, thank you.
