Ok, I'm going to be as detailed as I can here so that any questions you might have for me will already be answered...to try and speed things up.
I recently registered a domain (http://gnawlidge.com). I have a subscription to Lynda.com, so I went through the instructions to install WordPress and configure a multisite. I have installed WordPress many times, so that part was easy. The multisite setup, I followed step by step along with the videos. I checked with Godaddy, which is where I have hosting (for now) and they do not support the subdomain multisite if you use a shared hosting account. I believe what they mean is if I have more than one domain on the hosting plan, which I do. There are 3 total.
So, I followed the instructions on setting up multisite exactly as they were told to me in the videos, and I worked right along with them the whole time. I have not yet added any other sites to it, I just went through the setup.
Everything looked great until I tried to click on the Hello world blog post. I got a 404 error. I played around for a bit and found that if I set my permalinks to default, it worked. I tried setting many custom permalink styles, but they all had the same effect. If it was anything besides the default, I could not see anything but the front page.
So I set the permalinks to default.
Then I went to add a new site. The site URL should be http://gnawlidge.com/guitar/
But I get a 404. I get a 404 when I type it in, and I get a 404 when I try to visit the site.
The questions I have are, Is there a way to fix the permalinks so I don't have to use the default? And What do I need to do (or what suggestions do you have) to fix the problem of not seeing the second site?
