#58222 closed defect (bug) (duplicate)

Upper case breaks WP home/url and no warning is given.

Browsers (at least Safari, Firefox, Chrome) will request when you enter Any upper case gets set to lower.

If you have a home url set like for example your home page will be completely inaccessible with 301 redirect to itself as browsers turn the upper case to lower case. It seems like that should be lower-cased for subdomains.
