Hello,
i found this on a forum and this help:
I had the same issue a few months back I tried this and this works for me.
define(‘FORCE_SSL_LOGIN’, false);
define(‘FORCE_SSL_ADMIN’, false);
define( ‘CONCATENATE_SCRIPTS’, false );
define( ‘SCRIPT_DEBUG’, true );
try to load wp-admin with SSL.After reloading it looks OK, maybe after re-login, set SCRIPT_DEBUG to false.
It helps, but now the header and footer from your theme doesn’t load 😉
regards
Patrick
