HELP! Blog broken :( Error 404 Not Found

Error 404 Not Found “Your browser cannot find the document corresponding to the URL you typed in.” That is the error every link on my wordpress blog turns back except the top level: https://askandrea.adamsweb.us

The content still exists. But my website visitors cannot access them.

My dashboard refuses to display anything besides the “Right now” box and just the header for “recent comments” I cannot delete spam users. The automatic upgrade/install features do not work in my installation. Virtually any plugin I upload via ftp does not work/causes errors.

I have already tried turning off and deleting plugins. I have to turn off ASKIMET (for cryin’ out loud) before the dashboard will display even half of what it is supposed to. That is the only issue turning off askimet helps with and obviously I have to have askimet.

I’ve tried upgrading to the latest wordpress, optimizing my database, repairing, restoring it to before that operation since I discovered the even worse problem I lead off with after that. I am at my wit’s end and everything just seems to get worse and worse. ?? The restore was to a point after the wordpress upgrade, note. I have a backup from before it downloaded to my computer, too. Though I’m not sure how to do it manually if I had to revert back. Note most of these problems predate the upgrade to the latest version of wordpress. The new problems are none of the pages/posts on my blog displaying and even askimet causing errors.
