Update to WP 4.7 is corrupting database

Hey Kookidooki,

Yes i confirm this error, I am also facing similar issue, while upgrading the database gets corrupt and now i am not able to add pages/plugins or upgrade anything. I am trying to get in contact with hosting company to get it fix.

Thanks,
Swayam

Hi,

If the database is acting up, you can usually sort this your self, we have a repair tool that you can enable to do this. The instructions are available at https://codex.www.ads-software.com/Editing_wp-config.php#Automatic_Database_Optimizing

It should be noted that this doesn’t necessarily mean it’s a WordPress issue (with millions of sites and so far only 2 reports of this, I’m quite happy with the numbers at the moment), but if you are on a shared host they might have been overloaded during the database upgrade, which may have affected your sites. The repair tool should fix that though ??

I can confirm that I have the same issue after the update to 4.7

This error shows on the backend when I want to make a new post.

Warning: Creating default object from empty value in …/wp-admin/includes/post.php on line 641

Warning: Invalid argument supplied for foreach() in …/wp-content/plugins/wordpress-seo/admin/metabox/class-metabox.php on line 1056

I have the same after update to 4.7.2

I’ve added the following line to my wp-config.php file:

“define( ‘WP_ALLOW_REPAIR’, true );”

Then run the script “repair.php” located at “{$my_site}/wp-admin/maint/repair.php”

Return no errors in the BD, but the problem persist ??

Any idea?

I am having the same problem.
any fixes??

I have on solution for this that works. Download WordPress 4.5 and delete only the 2 directory’s with your FTP programma from your site:

wp-admin
wp-includes

NOT THE: wp-content DELETE thats your template and upload images.

Than place the new directory’s wp-admin and wp-includes from the WordPress 4.5 in your site.

Login on your site: WordPress ask you upgrade the database. Say yes. And your database is now good working with 4.5.

open in the wp-admin directory the file update-core.php delete the php code and save the file. Now the upgrades from WordPress is stopped.

If you will new WordPress upgrades on your site, place on new file update-core.php in the wp-admin directory from your 4.5 download and the upgrades to 4.6 or 4.7 works if the error is maked from the 4.7 in the future.

Hi All,

I am having the same issue.

Warning: Creating default object from empty value in /public_html/wp-admin/includes/post.php on line 641

Warning: Invalid argument supplied for foreach() in /public_html/modules/wordpress-seo/admin/metabox/class-metabox.php on line 1054

But I can′t fix it using the method: myisamchk, since my DB is InnoDB.

Please help, tried going back to version 4.5 but somehow it still not working.

I am not able to create posts, or new product on Woocomerce. Disabled all plugins and Theme, but it still not working. I need this working.
Please help ??

Hi all,

Got the fix for this issue:

Go to your phpMyAdmin -> wp_posts -> Structure then got to edit (change) ID and check the A I (auto increment) -> Save.

That fixed my DB, now I can create new posts and duplicate woocomerce products.
This is very exciting. Please do a backup before proceding.

Thank you!

ok thanks for the 4.7 solution

@gonniac You rock !! you made my day, thanks a lot !!!!

Still i would like to add something :

If you get an error form PhpMyadmin trying to check the “A I” option, you have to make the ID row an index before you edit it properly.

Cheers

Thank you for the solution! I had the same problem. When I fixed the AI in post field of the database I can create posts and pages with no problem. But the problem remained with creating users. I still can not create the new one. Did anybody faced the same?

I don’t no wat the problem is, but you can in your wp-config.php this text set to true.

define(‘WP_DEBUG’, false);/* That’s all, stop editing! Happy blogging. */

example: define(‘WP_DEBUG’, true);/* That’s all, stop editing! Happy blogging. */

maybe you find the error and you can make it.

meself i have not that problem.

I have TRUE in this line.
Where can I see the error description?
In fact there is no error appears – but just after I save new user from WP admin part it does not apears in the list.

Ok have you not on error in the top than its ok.

Maybe you can try the new version from WordPress 4.8. You can download it here.

https://www.ads-software.com/download/

Go to you your FTP client and change the directorys and files in 4.8 version.

wp-admin
wp-includes

change files below in 4.8 version:
index.php
wp-activate.php
wp-blog-header.php
wp-comments-post.php
wp-commentsrss2.php
wp-cron.php
wp-links-opml.php
etc…

NOT the wp-config.php

And NOT the wp-content directory thats your themes important is the wp-admin ans wp-includes and below files in the root.

Ather that login in your wordpress site than ask wordpress the database is change say yes ok change it and than it must good work.

Stay the problem than its maybe on plugin or theme problem.

Thank you but I already have 4.8
I switched off all plugins and tried the default theme but the same problem remained.
