I will try to remove the 443 redirects as soon as I can.

In the wp-config.php, if I change this line:

define(‘FORCE_SSL_ADMIN’, true);
to
define(‘FORCE_SSL_ADMIN’, false);

then I can see the login page and I can use the “Backend” link as a network admin.

No, no changes were made to the server. I am the only person that ever logs into the machine and I know I didn’t do anything with the server.(I know, you heard that line before.) I did look at an fopen issue, but I put eveything back the way it was before I started posting here. Once something is working, I try to leave it be. I know that the security certs are due to expire in October but I don’t see the connection betweeen something that will expire in the future and something that is not working now.

Based on my above post, at least I know the trouble is related to a security thing. I also received a suggestion about looking at our AD Integration plugin. It is an older version and should be updated.

If it is truly a security issue, why doesn’t the page display and then give security errors or warnings? Why would the browser just decide to not display the login page? Anyway, my problem now is to get the instances working again.

So, does anyone know why this line,

define(‘FORCE_SSL_ADMIN’, true);

works for the top level site but does not work with subdirectory sites?

I think I may have found the trouble. Once some users confirm things are working, I will post the solution here.
