I cleared everything out. Downloaded WordPress again, and went through the steps again. This time it worked!
I think there might have been an issue with the wp-config file. The one I edited last time did not look the same as the new wp-config-sample.php file that I edited this time.
One other slight change this time – I put the files in the www folder rather than the public_html folder. Not sure if that made any difference. Like I said, I think it was an issue with the previous wp-config file that I used.
Thanks for the help.
I was a little unclear on the twohills part. twohills is a name the host site gave me. The username that I created for my database is twohills_brian. I think the question I had on that part is: why is the site trying to access one of my internal files rather than run from the public_html folder?
I think I’ve done something else wrong, but I can’t figure it out. solfood seems to have a similar problem.
