Thanks, Shane. I’ve got

I added the line I was missing (ErrorDocument 404 /index.php?error=404), but still no-joy. I’m able to access the subdirectory, but the file in particular that I’m supposed to load in order to install this other CMS still comes up as non-existent — even though I can take a copy of that file and download it to my computer.

I haven’t worked updated the blog in a while, so I might just uninstall it after backing up all of the appropriate files. This way, I can complete the installation of this other CMS and reinstall WordPress if I end up wanting to update.

Problem seems resolved. Blog is working, I can access the admin area of the site, and all in all I counted some thirty files that suffered from this problem before I stopped counting. Once I replace them, everything went back to normal.

No clue why the error started popping up, but this seems to have fixed everything.

Topic: resolved

Further Update: While reloading the vast majority of my files, I noticed that I was getting another error, but this time as I was replacing files. I was getting the following error:

An error occurred copying a file to the FTP Server. Make sure you have permission to put files on the server.

Details:
200 TYPE is now 8-bit binary
227 Entering Passive Mode (66,45, 238, 226, 53, 95)
553 Can’t open that file: Permission denied

When this happened, the offending file would be removed from my server and my attempts to replace the old file actually uploaded an entirely new file (I wasn’t prompted to replace the previous existing file). This may account for why many of the files normally used when accessing the admin section of my site are now listed as “Not Found.”

I will continue to replace old files and root out all of the files with this error. This thread will be updated with my efforts for the people who continue to have similar problems.

Thanks, MichaelH, for your efforts. I logged out, removed my cookies, used a new browser (Firefox), used a different browser (IE7), haven’t changed the firewall, and was still unable to log in. Uploading new copies of the majority of the admin files allowed me to see the login page and attempt to log in, but the files needed to view the dashboard or even jumping directly to wp-admin/edit.php and wp-admin/post.php met with the same failure.

Adding the step of deactivating all plugins, I still am unable to progress.

I may attempt a clean install of everything (minus the MySQL databases), but I’m afraid that this will lead to more problems.

Update: I’ve done two things since this original post. I’ve done a repair of the database with no noticeable changes and I replaced the files in my wp-admin folder with a clean install. While the wp-login.php page is suddenly there, any attempts to log into the admin area results in the same error.
