I have come seriously unstuck on attempting to set up the multisite feature with a new domain that is not a sub-domain or sub-folder.
I have been following the instructions in a 'For Dummies' book and consulting the internet where necessary. Multisite installed without a hitch from my single WP install, version 3.5.1. I installed it in the document root and the intention was to add a separate domain using the MU Domain Mapping plugin.
However, having updated my .htaccess file, changed over the DNS and added the new domain I have encountered two main problems:
1. Firstly, when I navigate to my original website the following message is returned:
"Too many redirects occured trying to open ....".
2. Secondly, the new website is loading with the standard WP homepage. However, I can't access the dashboard. If I attempt to navigate to /wp-login I get a 404 error and a redirection to my web host.
I've spent a fair amount of time on Google trying to remedy this problem myself but to no avail. Any ideas would be greatly appreciated. I get the impression that I either have an error on the .htaccess file or even the database from what I have seen on Google but Idon't know how best to proceed!!!
