I just checked and all of the files are in the ftp, but I think WordPress is somehow pointing to the wrong subfolder. The subfolder with all of the files, which is set with my host to be the main folder for this URL is /langdonlibrarytest. This folder contains all of the stuff that I’ve done to the site so far. There is also a folder called /langdonlibrarycom that only has a favicon in it. This seems to be the folder that is being accessed when someone goes to https://www.langdonlibrary.com.
I checked within all of the server settings for my host and they all are pointing to the correct /langdonlibrarytest folder. I’m not sure how to determine if this is the issue, and if so, where it is set up wrong. Since I can’t access WordPress at all I can’t get in to see if there’s an incorrect setting in there somewhere.
