I'm a self-hosted blogger who has been using WordPress on my site for quite some time now. I'm running version 2.6.2. Since yesterday afternoon when I made a post, something has changed. While the site is accessible, none of the admin files seem to be. wp-login.php, wp-admin/edit.php, and so on suddenly return the following error:
Sorry, but you are looking for something that isn't here.
I have changed nothing regarding my site or settings. The files are present when I log into the FTP and search the appropriate directories. This problem occurred as of this afternoon and I have found no other thread on this site that discusses the same problem. The only other post that I have seen detailing a similar problem (WP Login Redirect) has yet to be answered.
I find it exceedingly strange that my site remains functional, yet I'm unable to access any of my admin files even though I was capable of doing so just yesterday afternoon. I have made no changes at all to the site beyond posting for a couple of weeks now. I do not have a backup of any of my files or of the database due to my prior antediluvian computer failing in a spectacularly messy fashion -- along with my previous backups.
Thank you in advance for any assistance that people may offer. I will be adding this thread to my feedreader in order to follow any updates.
