AkashicHi.
I'm getting the redirect loop when I try to login on a blog with the underscore in name - only when using Internet Explorer. When trying to login on a http://sub_domain.my-domain.net site, 'standard' redirect loop occurs.
Firefox and Safari are perfectly fine - no redirect, no error in logs. Also logging on other subdomains (without underscore) is working.
I have deactivated all plugins and mu-plugins as well was clearing the cache every modification I made.
.htaccess is not modified. I've tried to fix the problem with altering the regex but that didn't help.
As for now the only solution is to change the underscore to hyphen, but I'd like to avoid doing it.
Wordpress is up-to-date.
Any ideas?
Or anyone gets same error under similar circumstances?
Best wishes,
A.
