WordPress dashboard error messages

Hi,

When I go to ‘Appearance / Customise’ page of the WordPress dashboard panel, I get a dysfunctional page filled with the following error messages:
Notice: Trying to get property of non-object in /home/shishkeb/public_html/wp-includes/nav-menu.php on line 780
Notice: Trying to get property of non-object in /home/shishkeb/public_html/wp-includes/nav-menu.php on line 784
See screenshot: https://postimg.cc/9zKJHBqK

When I go to ‘Plugins / Add New’ page in the WordPress dashboard panel, I get a page that begins with 10 lines of the following error message:
“Notice: Undefined property: stdClass::$plugin in /home/shishkeb/public_html/wp-includes/class-wp-list-util.php on line 150”
See screenshot: https://postimg.cc/2bP8rJYV

What is causing this and how can it be resolved?

Regards,

Yunis

P.S. Plugins are not the problem as the problem persisted after all of them were deactivated

This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

If you can install plugins, install “Health Check”: https://wordpress.org/plugins/health-check/ On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site. You can then use its admin bar menu to turn on/off plugins and themes one at a time.

See http://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/

Steven,

I disabled all installed plugins, reverted to the TwentySixteen theme and the issue is still there. It did not make any difference.

What could be causing this and how can it be resolved?

How are you hosting your site?

Maybe your WP install is messed up. Try a manual reinstall:

Steven,

Is the manual reinstallation of WordPress different than doing a “Re-install Now” from the WP dashboard panel?

So much for that idea.

How is your site hosted?

Steven,

It is hosted on at a normal webhost for WordPress managed websites i.e. tsohost.com

Is there any caching involved on your site, either through plugins you’ve installed, plugins the host has installed (mu plugins) or at the server level?

Your hosting provider has a post about how to edit your PHP.INI file for your account here:

https://www.tsohost.com/blog/php.ini-the-small-file-that-makes-a-big-difference

Specifically, point number 6 there tells you how to disable the reporting of notices and warnings on your site:

error_reporting = E_ALL & ~E_NOTICE & ~E_WARNING

Samuel,

My webhost changed the setting of the PHP.INI file to “error reporting to E_ALL & ~E_NOTICE & ~E_WARNING’ and nothing changed. The error messages are still there.

Do you have WP_DEBUG enabled in your wp-config.php file?

Steven,

In the wp-config.php file I have the following statement included:
“define(‘WP_DEBUG’, true);”.

Change that from true to false.

Steven,

I changed the “define(‘WP_DEBUG’, true);” to “define(‘WP_DEBUG’, false);” wp-config.php file like you advised and it worked. Thank you very much. The error messages in those dashboard pages have disappeared. You saved me from being on the verge of doing a clean WP re-installation. Thanks.

Regards,

Yunis
