Title: Login issues… Last modified: August 20, 2016 --- # Login issues… * Resolved [jeremy2805](https://wordpress.org/support/users/jeremy2805/) * (@jeremy2805) * [14 years, 4 months ago](https://wordpress.org/support/topic/login-issues-13/) * Hi, * I created a blog recently, then installed multisite, then added a couple of new blogs. The original blog was [http://www.domain1.com](http://www.domain1.com), with the new blogs being blog1.domain2.com and blog2.domain2.com. * Everything’s working fine with domain1.com. I can see the hello world entries for blog1.domain2.com and blog2.domain2.com, but whenever I try to start work on either of the new blogs, I get shown the login screen, enter my credentials, but just get presented with the login screen again. * I’ve installed the wordpress-mu-domain-mapping plugin, but have a problem with the domain options checkboxes (each time I hit save, they all get re-ticked.) From reading the posts about the plug-in, I suspect that’s a symptom rather than the illness. * Cookies cleared, cache cleared, tried from different browsers/computers/etc.. * My questions are as follows… * 1. When I enabled multi-site, the network admin couldn’t use the wildcard on domain2 as it is already in use for something else. We don’t allow on-demand blogs (and I inferred from the documentation that wildcards are only required when on-demand sites are enabled). We used a web-routing entry for each blog within domain2. Is that an issue? * 2. The entries for [http://www.domain1.com](http://www.domain1.com), blog1.domain2. com, and blog2.domain2.com all point to the same folder. Is that right? * Any other suggestions? * Many thanks, * J Viewing 5 replies - 1 through 5 (of 5 total) * [WPtesting](https://wordpress.org/support/users/wptesting/) * (@wptesting) * [14 years, 4 months ago](https://wordpress.org/support/topic/login-issues-13/#post-2504261) * > new blogs being blog1.domain2.com and blog2.domain2.com * > Everything’s working fine with domain1.com. * > The entries for [http://www.domain1.com](http://www.domain1.com), blog1.domain2. > com, and blog2.domain2.com all point to the same folder. * It seems a mess. According to your description domain2 should be your root domain of multisite. What’s domain1 then? As you have mentioned both point to the same folder, are you redirecting domain1.com to your root blog(domain2.com)? * Thread Starter [jeremy2805](https://wordpress.org/support/users/jeremy2805/) * (@jeremy2805) * [14 years, 4 months ago](https://wordpress.org/support/topic/login-issues-13/#post-2504269) * Hmmm…in what way is it ‘a mess’? * Are you saying that having two domains is not possible? What is a root domain and a root blog? I see nothing about them in the instructions I followed ([http://codex.wordpress.org/Create_A_Network](http://codex.wordpress.org/Create_A_Network)) * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [14 years, 4 months ago](https://wordpress.org/support/topic/login-issues-13/#post-2504287) * You can map multiple domains to any site on your network _except_ the main site. * That said, there’s a known issue with the domain mapping plugin (I think it’s actually a bug in WP, but Ron’s working on it). Grab the DEV version of the plugin from [http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/download/](http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/download/)( download the … one labeled development version 😉 ) and see if that helps some. * Which domain is the ‘main’ domain where WP was installed? If that’s domain1.com how did you ‘map’ domain2.com, AND blog.domain2.com and blog2.domain2.com? Are you using a multi NETWORK install? * [WPtesting](https://wordpress.org/support/users/wptesting/) * (@wptesting) * [14 years, 4 months ago](https://wordpress.org/support/topic/login-issues-13/#post-2504327) * Root domain = Main Domain, likewise Root blog = Main blog (BLOG ID = 1) * And, NO! you can’t set multiple domains as a main/root domain. * Thread Starter [jeremy2805](https://wordpress.org/support/users/jeremy2805/) * (@jeremy2805) * [14 years, 3 months ago](https://wordpress.org/support/topic/login-issues-13/#post-2504446) * OK, I resolved this one and I thought I’d best document it…. * Firstly, whilst the MU domain mapping plugin doesn’t seem to like entries for the primary domain, it accepts mappings for others. * Secondly, and the one that fixed the login issue from the OP, in wp-config.php, SUBDOMAIN_INSTALL was set to true. Setting it to false fixed the issue. I’m not sure why as I have created a subdomain multisite network, but it works. * Thirdly, my sites are working without the DNS wildcard being used, so I’m fairly confident that it is used purely for on-demand sites (which I have disabled.) * So, one installation of WordPress. Sites at [http://www.domain1.com](http://www.domain1.com), blog1.domain2.com, blog2.domain2.com, blog3.domain2.com, etc.. * Thanks to everyone who didn’t say it wasn’t possible.
