Here's the story: Last week I logged into WordPress, and I installed a few updates for plugins. At one point I accidentally navigated away in installation - I think this is where the problem began. My website came up as a blank white screen and my login page was "Not found The requested URL /wp-login.php was not found on this server." So I went onto FTP and tried to just delete the plugin. That didn't work so I re-installed WordPress from FTP and deleted all my plugins. I used the newest version (I hadn't updated since maybe 2.9...not sure). After I replaced the old WordPress files, everything came back up - including all my posts, pictures, etc.
...But then a couple days later I went to log in and I had the same problem, except now it's saying there is no website at that address. So again, I reinstalled wordpress from FTP, but this time the problem wasn't resolved. Over the last week I've been trying everything I can think of (and searched the forums) but can't get the site back up. And today, for some bizarre reason, I can't log on to my FTP server. It's saying the login is incorrect. I'm stuck - there's really nothing I can do at this point.
And the icing on the cake is that I didn't set this blog up originally. Our web guy did about a year ago - and we've since cut ties with this person. I'm not sure who is hosting it, and I have no idea how to access PHPMyAdmin.
Any suggestions would be greatly appreciated. I am SO frustrated right now!
