I have just upgraded my self-hosted blog to the latest version of WordPress, and now I can't access admin. I receive this error message:
Warning: require(/home/content/98/7319198/html/wp-includes/date.php) [function.require]: failed to open stream: No such file or directory in /home/content/98/7319198/html/wp-settings.php on line 117
Fatal error: require() [function.require]: Failed opening required '/home/content/98/7319198/html/wp-includes/date.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/98/7319198/html/wp-settings.php on line 117
This message also appears on my blog posts. http://whoisjonleuty.com
Any help would be much appreciated.
