Hello,
I noticed some others were having this issue but didn't find an answer that worked and/or applied to my situation (i.e. unlike some others, nothing else is installed on my server, I'm running in the root directory, etc.)
See: http://clevelandhistory.org
So yeah, I'm getting these 404s on pages in the wp-admin directory.
One guess would be .htaccess. The install failed to create a new one.
This could be a result of my inability to 777 the root directory, for lack of access via FTP.
Also, as far as I can tell (by speaking with GoDaddy support), I do have the * subdomain setup, even though I was given a warning after installation.
Any help would be greatly appreciated.
Cheers -- Erin
