I ran into a problem when I added a second WordPress blog network to my server. I had the Curious Cat Blog Network up and running for quite some time with sub-domains for each individual blog in the network. WordPress automatically dealt with routing the sub-domains and having urls work. It really is very nice how easy it is to create a new blog and have everything up and running – just add it in WordPress, no need to touch the server directly. Blog networks are a new feature in WordPress 3.0 (I think) which are very nice. I would imagine it builds on effort with Wordpres MU but it is just part of regular WordPress now.

When I added the second blog network however the new faux-sub-domain that should be used affordable-funeral.moneyite.com would instead be redirected to curiouscatnetwork.com and since no such domain existed on curiouscatnetwork.com it gave the standard error message WordPress generates for the case where a sub-domain url is not recognized.

The main domain for the new site was working: moneyite.com. I tried searching around for some solutions to this problem online but couldn’t find any. I am not sure if multiple wordpress blog networks should work on the same server without any special needs. But it wouldn’t for me. I found a solution that did work so I will share what worked for me.

I created new sites-available records for each of the sub-domains and once you reload Apache everything seems to work. I am not sure their isn’t some problem with doing things this way that I haven’t uncovered yet. But it is working for me so I wanted to share this in case it can help anyone else trying to use multiple wordpress blog networks on one server.
