There is a Flaw with update to WordPress version 3.6
of the 114 site 57 had this error after the update:
Warning: require(/home/sitename/public_html/wp-includes/revision.php) [function.require]: failed to open stream: No such file or directory in /home/dhomepla/public_html/wp-settings.php on line 120
Fatal error: require() [function.require]: Failed opening required ‘/home/sitename/public_html/wp-includes/revision.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/dhomepla/public_html/wp-settings.php on line 120
Please note sitename was added as a place holder for the directory name of the affected site.
This error is fatal to the wordpress site being updated.
What appears to happen:
Revision.php is randomly missing and is not unpacked during the update and the update fails.
- get the latest version of wp : http://wordpress.org/download/
- upload the WP-Includes files over-top of the broken version
- then log in to the admin side and force a reinstall of wordpress.
- Restore last working version of wordpress database and files.
What a pain.
