Thanks Phil, I’ve made a little progress!
I made a fresh installation of wp, then ftp’ed my wp-content folder into a subdomain. Now instead of the Error message, I’m getting a blank white screen. I am able to access the database through phpMyAdmin, so that’s a good sign. I’ve attempted to check my wp-config file, but (as pathetic as this may sound), I can’t find it anymore. Where SHOULD it be located? That might be my issue?
If it helps you investigate, my new content files are at desmoinesfeed.com/test/wp-content.
Many thanks!
