I have first installed with
Sub-domains (like blog1.example.com)
then I realised I made a mistake, I deleted wp-config, the database and restarted again with
Sub-directories (like example.com/blog1
It created everything but when trying to login I got this
Redirection limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.
So I deleted everything the domain, the directory, the database and reinstall and still the same error message that's crazy !!!
I have lost several hours with this why on earth does it behave like that ?
Any solution ? Thanks if someone is a genious enough to know what's happening.
