Dear WPMU Dev Team,
Would you please try to access my subdomain via wp-admin or through my Network Admin as it always returns a 404 Error? Support access has been granted to WPMU.
I have already successfully set up several MultiSites, but on this account I am facing the problem outlined above.
I have also gone through all your recommendations prior to writing this email. This MultiSite set up uses the latest version of Wordpress, Plugin & Theme tests did not make any difference and the Network Set Up parameters (.htaccess and wp-config) have been configured according to the guidelines.
I thank you in advance for your kind support in this matter and send
