As of January 16, 2011, it appears that I have been able to fix this issue.

If anyone’s good with WordPress, please holler. I’m having real issues and can’t get them resolved. Issues include:

• comments not posting
• links not resolving
• posts not updating
• ‘read more’ not ‘readmore-ing’

I tried:

• switching to the Twenty Ten theme to rule out any theme-specific problems?
• resetting the plugins folder by FTP & phpMyAdmin
• deactivated ALL PLUGINS
• re-uploaded the wp-admin and wp-includes folders from a fresh download of WordPress

Also, on certain, definitely not all, posts when I go to either save or update (I’ve resorted to entering many of my posts manually through phpmyadmin) posts from the WP Admin interface, I get taken to a ’404′ public page with this  admin (private/password protected) URL:

http://kitlas.com/wp-admin/post.php

Also, i get that same “’404′ public page” on some posts when I click the ‘Read More’ link or if I try to open that post directly from the WP Admin interface.

I tried this fix:

Solving “headers already sent” warnings

But it didn’t help.

I first thought it may be to post length, then i thought it was the ‘<–more–>’ code but that’s not the case. I’ve also deactivated all plugins too and have had no differing result.

….help….
