ebhead on "White screen of death after ugrading to wp 4.6"

using current plugins, and vantage theme. updated remotely. went to my backups list and that's the only site I haven't yet found a recent backup for by some fluke.

can't access admin areas (to be expected with WSOD).

so far, I've taken vantage out of the themes folder and put in a new version of 2016 from file manager (cpanel) to no avail.

I've renamed the plugins folder to no avail.

Other than restoring from a backup, what else is recommended?

Does your site have an error_log file in the root, if so, what are the last few messages in it (open with any text editor).

You can also try enabling WP_DEBUG. If you're lucky you might get an error message instead of a white screen.

Just enabled it...

Warning: require(/home/mydomain/public_html/wp-includes/class-wp-post-type.php): failed to open stream: No such file or directory in /home/mydomain/public_html/wp-settings.php on line 160

Fatal error: require(): Failed opening required '/home/mydomain/public_html/wp-includes/class-wp-post-type.php' (include_path='.:/opt/alt/php54/usr/share/pear:/opt/alt/php54/usr/share/php') in /home/mydomain/public_html/wp-settings.php on line 160

I'm having my host restore from a recent backup for me, thankfully, but I'd still like to know for furutre reference. thx.

p.s. if they succeed in the restore, I'll mark this as resolved. if not, I'll need to continue troubleshooting.

Sounds like the update didn't complete for some reason. If it occurs again if you try to update, you might have permissions issues. Go through this article to confirm they're correct.

I have the same problem.

Thanks, Jacob. Corienb, I had the host restore a recent backup. Then, I made another backup of that restored one. Then, I re-ran the WP update and it finally worked.

I can't transfer the file it's complaining about (/wp-includes/class-wp-post-type.php), tried via FTP as well as the host backend filemanager.
Tried renaming, resaving the file. Ugh.
