I followed the instructions on how to change my URL so that it does not use the /Wordpress at the end. It didn't work so I changed everything back but now I cannot do anything in WP without this message coming up - I can't even save my general settings so that the WP Address and Site Address both have /Wordpress. When I click on save settings I get the The "requested URL /index.php was not found on this server." message. I'm REALLY worried I've list everything (I do have a copy of WP files on my desktop). I am in FileZilla and everything was put back as it originally was - the index.php file is where it was.
PLEASE HELP as I cannot now do anything to my site - I cannot get off the general settings page even.
