I am having issues that seem to be related to trying to change a multisite installation to use www.
The site was initially setup without the www. I added code to .htaccess to redirect all urls to www. I changed the site the 'DOMAIN_CURRENT_SITE' to www.domain.net.au. I change the siteurl & homeurl in the db for all of the sites in the network to reflect www.domain.net.au.
Everything appeared to be ok until I tried to access the Network admin menus. http://www.domain.net.au/wp-admin/network. FAIL. ERR_TOO_MANY_REDIRECTS
I then restored all of the settings back to domain.net.au. I now can access http://domain.net.au/wp-admin/network but if I try to access the network install plugin page http://domain.net.au/wp-admin/network/plugin-install I am logged out & redirected back to the login page.
I noticed that the url above is www. even thought I have reverted to non-www settings.
Would appreciate some help with this preferably with the www working.
