PozHonks, similar issue here.
I worked all day, copied a complete mirror of my whole /public_html/blog directory to my hard disk, uploaded some themes, and opened some windows while using Dashboard (I’m NOT here at Global, my WP is set up on my server; I have Admin)
and I was changing Themes in THIS window, while VIEWING the changes in THAT window… and registered a New User in one of the new Themes… but it STILL saw me as Admin, even though it sent me an email with my new Password (random).
When I went to the Dashboard/Themes window, I clicked on Plugins and immediately got an error message on an empty, white screen…
THAT was the Beginning of Sorrows.
I can’t Log In, can’t seem to overwrite the proper wp-config.php or config.php or whatever I have to do now to “Establish Contact with your mySQL database”
Help?
