Hi,
Try the fixes suggested at following thread:
https://wordpress.org/support/topic/404-error-after-edit-gt-update-post
If this does not fix your issue, ask your web hosting provider and try disabling mod_security for your account.
Thanks,
i didn’t worked for me i tried all the steps and edited my .htaccess file.
Hi,
Try Following suggestions:
Deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
If you can’t get into your admin dashboard, try resetting the plugins folder by FTP or PhpMyAdmin (read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help).
Switching to the Twenty Fifteen theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via FTP so the only one is twentyfifteen. That will force your site to use it.
If all suggestion fails, ask your web hosting provider for server logs as 404 error is coming from web server.
Thanks,
last night i rolled by to WordPress 4.2.2 but there was no change, then i reinstalled 4.2.3 manually and now i can edit all the posts, hence the problem has been resolved.
Great to hear that your issue has been fixed.
